I always tell my kids that they will get in more trouble if they lie to me about whatever it is that they have done, than if they just told me the truth.
I was working yesterday morning, almost done with my transcription and the kids kept getting louder and louder. Several times I said "please be quiet, I'm almost done." finally I got upset "How many times do I need to tell you? Be quiet!" Little Man was standing there and said "Five." Then he turned around and went outside.
Such a funny kid ;).
