Defriending isn't banning. It doesn't mean that you don't care for the other person's thoughts, just that you don't want to see them on your Friends page every day. As you may remember, I've actively encouraged people to defriend me if they find they're not really reading my entries.

Banning is something else. It sends the message that you never want to hear anything that person ever has to say again ever. It's no wonder I take it a little more personally
