This guy hit on me yesterday.

What does one do in such a situation?  (A) Start talking profusely about “my girlfriend”. (B) Start talking profusely about “my boyfriend”. (C) Tell him I’m flattered but not interested. (D) Tell him I’m flattered but not interested and also am not gay. (E) Scramble a lot with a dumb-founded face, with perhaps the self-effacing perhaps (my) self-esteem dehancing question, though perhaps just a legitimate scratching of sheer curiosity across a sub-cultural chasm – “Just curious… what do you see in me?”
