I would say I'm pretty polite. I don't like to cause offence if I don't mean it. That doesn't go to say I get all funny around people, though I like to keep the mood light-hearted and prefer not to have any tension.

I think it shows courtesy to be conscious of how one's behaviour affects others.

Edit: It just dawned on me how gay that sounds. Just for the record, I'm not some little fairy prancing about straightening peoples' ties. I just prefer to get on with people and choose to assume everyone is cool until they prove otherwise.
