Yeah, memory can be a funny thing, and the older I get the funnier (in a gallows humor sort of way) it gets. For instance, I would have bet money that we have bought Jiffy brand peanut butter in the past.
And I would also have bet money that in the Forrest Gump movie that the phrase was "Life is like a box of chocolates." Connie and I have watched that movie several times and said that quote between us MANY times in various situations. But guess what?
The problem with losing your memory is that you can't even remember what it is you might have forgotten.
I've heard people say "That guy has forgotten more than I will ever know." I used to think that was a compliment, but now I'm not so sure.
