When people casually ask "So who's the top and who's the bottom?"

It never fails to amaze me how people (straight, gay, etc) just throw this question out there as if a) it's any of their business and b) we have to answer them! And if we don't answer? Oh don't worry they'll try and guess and make things extra uncomfortable!Always amazed me how people don't understand the inappropriateness of this question.
