 I have a bike tire pump because I go biking and I'm always afraid my tires can be flat. Do you guys have something interesting in your backpack? A receipt from two and a half years ago from high school. But it's my favorite thing is my good luck charm. Whenever I need some good luck in class I pull it out. Probably my stethoscope. What's the most interesting thing in your backpack then? I have a Cody Coast watcher in my backpack right now. This packet of honey I took from the cafe earlier this morning. Oh, how many fan? I have a little lint roller. Probably my liver pen or a keychain. I have this little mirror. Oh, cute.
