If there's a girl/guy that I like I...usually don't talk to them at all. Nerves of styrofoam. Yeah, I suck at this...
...well okay, what I mean by that is if they're standing across the room at a bar or something, I won't be the one to approach, I never can work up the courage to make the first move (and frankly I don't see why that has to be on me to do that, but that's getting into a whole other debate). However, if someone's talking to me or I'm in a working kind of environment, I suppose I 'keep it real' just keeping along the lines that I'm expecting nothing to happen from this. I suppose I'm rather paranoid about this sort of thing, having a slightly Occam's Razor approach in that I make absolutely no assumption (or enough to act on it) that they might be into me unless given a highly conspicuous sign and then being beaten over the head with it. So yeah, I make no attempt to flirt or steer the conversation into that kind of domain unless presented with an indisputable indication of attraction that even my feeble brain is capable of registering. Even then my version of keeping it 'real' is to maladroitly stumble around the conversation, desperately trying to conjure some point of discussion and then running out of something to say 10 minutes in. Basically, I'm an idiot. And I suck at this.
