um...how the hell did I get THAT?

Recently I had a bladder infection for which I was forced to swallow copious amounts strong-ass antibiotics for a good two weeks. Well, my lab results came back and my urine showed traces of e. coli. Now how the f*ck does a vegetarian get e. coli? And how can you not show symptoms of it? The only way I can think of is if I had lunched on the tootsierolls in the kitty boxes. Unless I've been sleepwalking in a very, very hungry state, I just don't think that has happened...although my mouth has tasted like shit a couple of mornings... Anyway, more pee in a cup for me to see if there's a little family of mobsters setting up shop in my bladder. Why can't daily life be boring?
