Which Friend(s) do you identify with? Which would you like to hang out with or date?
That's actually three questions. I've been pondering them lately, and here are my own answers:
I hate to say this, but I'm probably the most similar to Monica -- hopefully not as pushy, but details are important to me. I would definitely ask people to make sure they push the pen cap till it clicks!
As for who I'd most like to hang out with, probably Phoebe. She's laid back and she's interested in a variety of things.
And for dating, it'd have to be Ross (preferably the pre-moist-maker version). Joey and Chandler seem to be all about the sex (though Chandler's more subtle than Joey), whereas Ross seems to also care about the woman as a person.
