*This is going to be an incredibly childish post. You have been warned.

There are so many kinds of irritating people in this world. People who mooch off you. People who bitch about others. Backstabbers. The pompous, look-at-me-I'm-God's-gift-to-the-world types. Them who cannot admit that they are wrong. hey-you types. Those who cannot admit they are wrong even if they know they are and will go on prolonging the conversation just to make you give up. And end up making stupid, pointless arguments just to keep the conversation until the other person gives up in despair, or worse, starts believing he's wrong. Rude, insolent shmucks who'll do anything to gain a point, and refuse to grant you one.

What do you *do* when you meet someone like that?
