The thing is, getting hit on when I'm happily attached doesn't bother me. It's always funny (particularly when played out as above) to some degree. But while I'm in a relationship it serves as merely a humorous justification that yes, my man can feel proud to have me. Why thank you sir for telling me I have beautiful eyes! Yes, yes I am attached. Why thank you for telling me he's the luckiest man in the world! I think he is too.
But when you're very recently singleized (definitely not a real word but should be), it just feels dirty. Like a mockery. Like the man winking at me in the bar is the pointing finger to the population I now belong to...not the blissfully in love and floating above on cloud nine shooting rainbows down at crappy bar scenes. Now getting hit on, it's just soooo gross.
*And lets be honest, we never call it "getting hit on" when it's a man of substantial quality and charm. We then just call it "a chance meeting."
