There's this guy where i live who walks around town constantly with a briefcase and a surgical suit on. he sometimes goes to the hospital and pretends to be a doctor.... they kind of just usher him out, but he always walks around pretending to be an important doctor. it's kind of sad, actually. i met this really cool dude in the next town over today.... it was pretty exciting, as he doesn't know english haha. i have to try to remember spanish and we speak in horrible spanglish mostly. i'm drinking with him tomorrow probably
