You know what I'm up against.

I'm going to put up the damnedest fight I've got in me, but I don't want you to take any gamble on it.

Maybe I'll win, and then again maybe I won't.

Maybe I'll go down and out.

I don't know--I don't feel half as sure of myself as I did before I made that bobble in town.
Before that, I did kinda have an idea that all there was to it was to quit.
