Forgetfulness

Sometimes I do things and then forget that I did them. I think it happens to a lot of people. Maybe they forgot that they put something somewhere, like a pencil behind their ear. I forgot that I took a shower. Crazy, right? There is proof that I just took a shower because my hair is wet, but I don't remember taking the shower at all. This happens to me often, and it drives me crazy. Does this happen to you very much?
