I didn't mean to come off as condescending, but if I'm being honest, I absolutely think it's childish. When a kid shows off his autographs to his friends he's cool, if an adult shows off his autographs to his friends he seems, well, desperate. It just doesn't make sense to me. It's just a strange ritual to ask someone for proof of meeting them. Maybe I'm just not sentimental in regards to things like that.
