It's funny you mention ticket stubs, because I also have a similar collection, and I kind of treasure it. Before my Google tracking my every step, before Twitter, as the years go by, I have some record of what I was doing at exceedingly specific times and dates. It helps to structure my memories a bit more than I'd otherwise be able to. I scanned them all at once (in several pages), and it's sort of a map of my adolescence. I can jump across time. I would be sad to lose it. (Along with the photo of the tickets for my make-shift - and first - double feature of Everything Everywhere/Dr. Strange. Multiverse-themed, doncha know?)
