Soon after I moved to NYC I saw a huge bug in my apartment. It freaked me out so much I called a neighbor, (half-)hysterical ("half" for dignity's sake), who was disgusted that I got so exercised over a waterbug, something I'd never seen before. Not long after that, I had a mouse & found myself, without expecting it, standing on a chair like a lady in a cartoon. Since then I've gotten inured & when I had rats recently, all I did was yell at them. Only when they didn't cower & bolt did I call the exterminator. OK, they definitely made me jumpy but I was willing to live & let live, except they came out all day long. I guess I'm a New Yorker now.
