I think that we have two types of memory - snapshot and video.
My memory of the window in my room is definitely snapshot - I have no idea what I did before or after, but that single image alone was imprinted on my memory.
Whereas, when I was about 6, I heard and saw an argument between our neighbours. I remember clearly, he was telling his wife that she wasn't watering the lawn properly. She countered with, he was too stingy to buy a lawn sprinkler. He maintained that sprinklers didn't do the job properly. She asked why then did all the neighbours have one, and they were the only ones not to. Were they all stupid, and he was the only smart one in the estate? Shouldn't he be going round and telling all the others how to do it properly? He was wearing shorts and sandals. He had white hair and a white hairy chest, arms and back - I thought he looked like a polar bear. She was wearing one of those multicoloured print, shapeless, housedresses.
I was wearing green shorts with 4 pockets and a green button-up shirt in a sort of green tartan print and black leather buckled sandals.
A little incident of no consequence, but I have remembered it in detail this last 66 years.

Chas
