How about when you act like everything is about you. You say and do whatever you want, without regard to other people's feelings. Then people around you start to make it painful for you to continue. So, you decide you should probably change, because you don't really like that pain. And you start to realize that other people actually care that they are causing other people pain, and that realization bothers you.

But, all too soon, you forget all this, get involved with other people, and then that pattern starts all over again.
