I get tons of those -
You're a minister's wife? You must be brainwashed and subservient! (no, she'd hate that - and besides, until we met I was a pantheist/leaning Jewish and still am open to lots of religions)
You're a lesbian? You must hate men! No, only those that make those kinds of comments. Or ask to watch. My butch partner isn't your type, thanks!
You work in IT? You must be a programmer! No, actually, I do data modeling and tool creation. Can't even code HTML without a program. But thanks for playing!
You play video games? You must be into the violent ones! And have really fast reflexes! No, I play the Sims. A lot. And FarmTown/Farmville/Yoville/Cafe World. No reflexes there, bub. Sorry
You have a theatre degree? You must be so artistic and diva like! No, my degree is in technical theatre. And my M.B.A. is in technology management. Wanna see me puke? Try to get me up on stage.
You have an MBA! You must make a ton of money! I wish. Lowest pay on my team. Only one with a master's degree.
