As in tickets to gigs, shows, train tickets to places etc. I never ever keep anything like that. I went to see Derren Brown's live show (awesome show btw) with my best friend a few days ago, he asked if I wanted to keep the ticket. I said no, I have enough stuff in my room as it is, keeping tickets just means more clutter. He keeps everything like that, he has a box full of them. He says he keeps it for memories but, I have a brain :| lol that keeps my memories for me. I just don't see the point in keeping stuff like that. A lot of my friends do.
