Well I did one of those personality tests once and it said I was an INFP.
So I guess I wouldn't get along with people that had a combination of opposing traits.
I don't like people that are cold, or arrogant, or pushy/impatient.
My older brother is my polar opposite and we clash all the time.
Me, I'm rather laid back, I don't like to get angry, but my older brother is quick to anger and is pretty aggressive and intimidating. A bit of a mean-spirited bully actually.
The worse part is that he's completely unapologetic about it, about anything he does really... ¬_¬
I hate people that don't try to figure out a problem for themselves properly.
My older brother for instance will play a game, get stuck, then immediately demand I drop everything and help him. WTF? No, figure it out on your own, I did. >:/
Again, I hate being rushed or pushed to make a decision. I like to plan things out and take my time, to ensure I do it right.
In a cooking scenario, for instance, I like to do things slowly and try to be as clean as possible.
My counterpart however, likes to rush and boss people about and take over stuff, and not clean up or take care of anything.
(And I HATE people that don't respect other people and their stuff. One time at uni someone raided the freezer and ate MY chips. WTF? Did I give permission for you to eat them? Quite clearly they were in a bag that was not yours, what gives you the right to my property? I don't go around using other people's utensils, or eating other people's food, I expect some mutual respect here you bloody git. I don't go poking my nose into your business, so you leave me and my stuff clear alone, (asking me might help? ever think of that. Man, I really hate people sometimes... >:X))
EDIT: (You see with me, I don't have loads of friends, I don't trust easy, but the people I'm close to know that I'll do almost anything for them. If I don't know you, then yeah, I probably would say no if you asked to "borrow" anything of me, but if someone I knew, a friend asked, then yeah, I would let them no doubt. Its no big deal even if they didn't return the favour, because I know I can rely on that person in the future. Can a lot of people truly say that about their friends?)
