Warbaby,
I hear what you're saying. I know there are times that I've been like the sub you were describing...mouthing off to get "punished". I will certainly be the first to admit that I like to push the line between playing at misbehaving and *really* misbehaving, just to see what I can get away with. Punishment is like that, too. If all I get when I'm acting up is a swat on the ass, then I know he's not taking my misbehavior seriously (either it didn't bother him or he knew I was only playing at being naughty). On the other hand, just the right sort of look or a quick, sharp word can immediately bring all playfulness to a halt and get me back in line, pronto.
Okay...I think I'm done with the rambling comments for the day! *zips lips*
