What's My Name when I'm in trouble?

"Mommy, what's my name when I'm in trouble?", Benjamin wants to know. I'm unsure what he is getting at, but he restates the question. I assure him that he is not in trouble, and that his name is always the same, and that it's a wonderful name. Then he answers his own question, "Why do you call me Benjamin Luke when I am in trouble?" There it is. I've joined the throngs of parents who utilize the middle name for emphasis in a behavorial crisis. I'll try to vary my approach a little, so he doesn't come to fear hearing his full name - or maybe I'll need the extra clout with him.
