Eh - I don't think it's so much about the comment being offensive as it is about women hearing comments like this soooo often from guys who think they're being hilarious. shrug it grates after a while.
As for the rest, well, it can amusing to go out and get tipsy/hammered once in a while but I find doing it every night gets super tiresome and I start feeling really shitty in the mornings. It's interesting that you consider yourself a shy/socially awkward person though :) - it doesn't come across a lot in your blogs... Most people, as you say, really don't give a damn though. They're happily self absorbed enough to not give you a second thought.
As a woman, when a man jokingly tells me to make him a sandwich (if I am home) I grab 2 pieces of bread and place them over his ears like Gordon Ramsey and say..." YOU ARE A SANDWICH."
Yeah most of the time I’m really not. One on one situations I’m golden, even in a small group. It’s really the bigger groups where I don’t know anyone that I’m weak. But like anything else it’s just practice.
