I bet I'm not the only one who has said this. I bet some of you have even said it to an adult. And I even bet some of you have heard it said to you. I just bet.
I, though, said it to my 4 year old the other day in the van when, for some reason, he decided to call for me, say, "See, look," and pull his jeans down ever so slightly to reveal the top part of his underwear. Not sure exactly why he thought it necessary to that, I simply thanked him and turned around. He seemed satisfied with that and quickly replied, "You're welcome," and turned to look out the window. Not another word was spoken about undies for the rest of the ride.
