Memory is a funny thing. I can remember stuff from when I wasn't even two years old yet, clear as day, but a lot of that stuff I can't put into sequence.
I forgot our 19th wedding anniversary a while back. I damn sure didn't forget the 20th.
I know people who "remember" stuff the way it did NOT happen, but insist it did happen that way. I have to wonder if they're not just liars.
My dad used to say he could remember being born. He was a joker, but I often could not tell whether he was being serious.
