I've been re-reading High Fidelity lately (yeah, yeah, shut up) and the whole thing about what people are like versus what they like confounds me. I don't think it's a black and white situation, that what people like matters more than what they're like, or vice versa. But in my own personal experience, I do tend to be drawn more toward people who like the same things as me. Maybe that makes me petty and superficial??
For instance, on the rare occaisions I go to parties, I find myself talking to people about music because I'm rather shy and it's the only subject I feel I know enough about to discuss with others. When I find the one or two people at the party who have similar taste to me, I like them the best and end up talking to them the rest of the night. At a large party once I happened upon a guy that liked Captain Beefheart and, in my drunken stupor, I promised him a taped copy of my Lick My Decals Off, Baby vinyl. "Now here's a guy I can drink with, god damnit!!" I shouted to my then-girlfriend across the room as her guests looked perplexed back and forth between us.
I do think that what people are like matters a lot, too. I just am attracted to people who like the same things as me, and from there I see what they're like. Does this preclude me from people I could get along with really well but who like terrible music, books, and movies?? Well, this raises a whole 'nother topic of what makes for friends and lovers...is it having things in common, or being a like, both, or none of those?? But we'll skip that for now.
