Because I Said So?

Abby came home from school the other day and announced with a bit of irritation,
"Mom, none of the kids were obeying me at school today."

Me: "Honey, why did you think they should be obeying you?"
Abby: "Because I was there." (Duh.)

Yeah, that's our wish as parents, too.

*Incidentally, I found out it had been Abby's day to be in charge of something at school, so there was just cause for her irritation. Sure sounded funny without the context, though.
