Want to know something I hate that I bet has happened to you too? I hate it when you're talking to a group of people and one of them who isn't particularly a friend of yours starts talking about something pretentious and retarded, like what he thinks of people who have never heard of obscure French poets, or how many girls he's slept with, or something. So then later, you remark to someone else who was there who you thought was really a friend of yours but it turns out is at least also really a friend of theirs that you think this particular person seems like a jerk. And then the friend says this:
"Oh no, you don't understand! That's just how he is."
Oh, now I get it, that's just how he is! A jerk.
