There's an old crushed fortune cookie in the buttom of my purse. I tend to get those from Chinese buffet restaurants. By the end of the meal, I feel too full to munch on the cookie, so I just toss it into my purse and forget about it for weeks. Sometimes, when I am bored I will get that cookie and munch on the tiny pieces.
Medicine bottles. My daughter has abdominal spasms, and I keep a bottle of medicine in my purse in case we're out and about when she needs some. For some reason there are two bottle in there. I think I might have been meaning to take one to her grandma's and forgot? I also have two pairs of glasses, neither of them mine.
