How do you handle conflicts—talk it out or wait it out?

Been thinking about how people deal with disagreements lately. Personally, I'm more of a "let's sit down and hash this out" kinda person, but my roommate is totally the opposite—she'll just go quiet and wait for things to blow over. Drives me nuts sometimes, haha. Anyway, quick poll: when you're in a conflict, do you prefer talking things through right away or giving it some space first? Curious how other folks handle this stuff.
