The street was in London and the street was the same street for fifty years and the street was called Harrow Road and the street did not change and the people on the street changed and the change created the Doppler effect, which is the phenomenon where the frequency of a wave appears different to an observer depending on the observer's motion relative to the source, and the two observers were on the same street and the street was the source and the two observers were moving in opposite directions through time and the frequency of the street appeared different to each observer and both frequencies were correct and both observers were right in their own reference frames and the truth was relative and the truth was in the reference frame and there was no single truth.

The first timeline was 1925. The first observer was a woman named Margaret. Margaret was twenty-three years old and she lived in a flat above a bakery on Harrow Road and Margaret was moving forward through time and the street was new to her and the street was full of things that were happening and the happening was the frequency and the frequency was high because Margaret was moving forward and the forward motion compressed the waves and the compression made the frequency high and Margaret experienced the street as full of happening.

Margaret worked in a factory and the factory was on Harrow Road and the factory made parts for airplanes and the war had ended and the war was four years old and the war was over and the factory had changed from making shells to making airplane parts and the change was happening and the happening was the frequency and the frequency was high.

Margaret had a boyfriend named Thomas and Thomas worked in the factory and Thomas was moving forward through time and the forward motion compressed the waves and the frequency was high and Margaret experienced Thomas as present and available and Thomas was everything that was happening and the happening was the frequency and the frequency was high.

The second timeline was 1975. The second observer was a woman named Claire. Claire was fifty-three years old and she lived in the same flat above the same bakery on Harrow Road and Margaret had lived in that flat fifty years before and Claire was Margaret's granddaughter and Claire was moving backward through time in the sense that she was looking at the street and seeing what it had been and the looking was the motion and the motion was away from the source and the motion away from the source stretched the waves and the stretching made the frequency low and Claire experienced the street as full of memory and the memory was the frequency and the frequency was low because Claire was moving away.

Claire was retired. Claire had taught on Harrow Road for thirty years and the school had been demolished and the school was now a car park and the car park was the frequency and the frequency was low because the school was gone and the going was the motion away from the source and the stretching of the waves made the frequency low.

Claire had a daughter named Susan and Susan did not visit and Susan was moving forward through time and Susan was away from the street and the away motion stretched the waves and the stretching made the frequency low and Claire experienced Susan as absent and the absence was the frequency and the frequency was low.

Both timelines were true. Margaret experienced the street as full of happening. Claire experienced the street as full of memory. Both experiences were correct in their reference frames. Margaret was moving forward and the forward motion compressed the waves and the compression made the frequency high and the happening was real. Claire was looking back and the looking back was a motion away from the source and the away motion stretched the waves and the stretching made the frequency low and the memory was real.

The Doppler effect is a physical phenomenon. The effect is not subjective. The effect is real. The frequency shift is real. The shift depends on the relative motion between the observer and the source, and the motion is real and the shift is real and both observers are correct.

Margaret married Thomas. The marriage was in 1926 and the marriage was a happening and the happening was the frequency and the frequency was high and the forward motion of Margaret through time compressed the waves of the street and the compression was real.

Claire's daughter Susan did not visit. The non-visit was a memory and the memory was the frequency and the frequency was low and the backward motion of Claire through time stretched the waves of the street and the stretching was real.

Both sides were right in their own reference frames. Margaret was right. The street was full of happening. Claire was right. The street was full of memory. The truth was relative to the reference frame and the reference frame was the motion through time and the motion was real and the truth was real in each frame and there was no single truth and both truths were correct.

Margaret had a daughter. The daughter was Claire's mother and the daughter was born in 1928 and the birth was a happening and the happening was real and the frequency was high and the forward motion was real.

Claire sat in the flat above the bakery and she looked at the street and she remembered the school and the school was gone and the memory was real and the frequency was low and the backward motion was real.

Both timelines parallel and crossing. The street was the source and the street was the same and the street was different in each frame and the difference was the Doppler effect and the effect was physical and real and the frequency shift was real and the shift was caused by motion and the motion was through time and the time was the dimension and the dimension was real and both observers were correct.

Margaret's frequency was high. Claire's frequency was low. Both frequencies were correct. Both frequencies were real. Both frequencies were caused by the relative motion between the observer and the source. The source was the street. The observers were Margaret and Claire. The motion was through time. The time was fifty years. The fifty years was the distance and the distance was the motion and the motion was the cause and the cause was the Doppler effect and the effect was the frequency shift and the shift was the difference between happening and memory and the difference was real and the difference was correct in each reference frame.

Claire wrote about Margaret in a notebook. She wrote: You were on this street and the street was full of happening and I am on this street and the street is full of memory and we are in the same place and the place is the same and the times are different and the difference is the Doppler effect and the effect is real and the frequency shift is real and both frequencies are correct and we are both right in our own reference frames and the truth is relative and the truth is in the frame and the frame is the motion and the motion is through time and the time is the dimension and the dimension is real.

She kept the notebook. The notebook was documentation. The documentation was the record of the truth in her reference frame. The record was the proof of existence. The proof was the only defense against the erasure that comes when time moves and the street changes and the happening becomes memory and the memory becomes a frequency that is low and the low frequency is the Doppler shift and the shift is real and the record is real and the record is the proof.
