itt: culture shock.
it's not common in my part of the world to use scissors (utility-drawer) to prepare your food because of sanitary reasons and whatnot. however, while I was living on campus one of my roommates (a vietnamese guy) would keep putting his scissors in the sink with the rest of the dishes. i kept thinking "wtf" every time i saw it, whereas to him it was exactly the same as any other kitchen tool.
needless to say, i stopped trimming my pubes with his food-scissors.
