I hate when I discover that random, relatively unimportant "facts" I had in the back of my mind turn out not to be true. It makes me wonder if reality is quietly morphing around me and rewriting history when I'm not paying attention.
For example, Richard Pryor died in December 2005. But for some reason, I thought it was a lot longer ago then that, like '99.
And Bob Newhart is still alive... I could've sworn he died like 6 or 10 years ago.
Maybe it's just that when I learn a new piece of information, it pushes something else I knew out of my brain. Or I'm just getting old.
