Shirts Made of Nylon

The ways of human memory are mysterious. Why do I remember some distant events and not others? We usually remember traumatic, dramatic events.  But not all, as it turns out. The one inch long scar on my left wrist, how did it get there?  I have to strain a bit to recall.  I was reminded of a surgery I once underwent, how could I have forgotten it?!  I had to remind my friend J. of an adventure we once experienced. He had forgotten it.  My friend P. reminded me of a misadventure I once had that he witnessed and that all our mutual friends remember.  I recall visiting my then friend, a Bolivian Indian who told us his name was Johnny Pacheco, the same as a band leader (though we were never certain that he was called that) at his apartment house's rooftop swimming pool.   But I don't remember anything of Johnny's apartment, which I would have had to enter first before going up to the roof.  Did it really happen, or am I making this memory up?

And so on.  Still, once you are reminded of something you remember it for all days.   My friend K. reminded me how we once teased a mutual friend of ours (whom I have completely forgotten) over his preference for nylon shirts.  Evidently, I initiated this at times cruel game.  Ten years later after that episode (of teasing), and not remembering any of it, I noticed and wondered about my boss' habit of wearing nylon shirts.   He was OK otherwise, drove a Porsche 911, gave me a break when no one else would , was a super guy, but these shirts!  Did I have a phobia about nylon shirts?  If I did, the change of fashion trends has apparently cured it.
