My favorite it still, after confronting me at work and "apologizing" in the form of telling me that everything that went wrong was my fault, but he'll take me back and give me another chance because he's such a great guy...
ME: How many more second chances do you think I should give you? You've used them all up. I don't have any left.
XABF (shouting to my back as I walk away): Yes you do! Don't lie to me! You've got lots left!
Let this be a reminder, the more we give, the more they want.
