two.
i was out at the local watering hole and the bartender introduced me to one of his old friends. she was quite attractive. we started talking and i'm not one to talk up the med school aspect of my life. however, my friends always seem to drop my "M-bomb" for me. so of course, my best friend starts bragging to her about how I'm in med school... blah, blah, blah. so she turns and asks me where I go and what year. i say that i'm a first year at UMD (this was last year) and proudly think... all right. she's into the med school thing. she then says... wow, i'm a PEDS attending there. i'll probably be teaching you in two years.
OUCH. priceless.
