If I did something wrong, to anyone, and I was truly sorry and ashamed for it... I would beg for forgiveness.

If I was in a serious relationship and my chick had some sort of fetish/fantasy that requierd me to beg, I'd do it to please her. As long as she expresses the same concern for my happiness and fulfills my outlandish demands.

If the economy got worse and I found myself living on the streets, I'd beg for help.
