Oops

All the kids are in bed.
We hear one coming down the stairs.
It is Dave, for probably the fourth time.
"Why are you up, what is it?" we say.
Dave says, "Andrew never tells on me anymore" he brags.
"Well, is there something that you are doing that Andrew should be telling us about?"
Dave gets a guilty look and realizes he's been caught.
"Yes, I was playing with a little Lego piece."
