Ah yes. I remember my relationship with "him" quite well.

Mid-fight:

Him: "That's it, we each get to punch the other as hard as we want, just once"
Me: "Fine."

I had a pea sized red spot on my thigh, that disappeared after 10 minutes.

He had a green and purple bruise on his thigh.

Obviously, he is much nicer than I. Or just less violent. I guess sometimes violence is, in fact, the answer.
