"Oh, a bunch of us stayed for math help".
My first thought was, "good for him, staying for extra help" when it SHOULD have been "Wait a minute, this kid is a whiz at math and is normally ahead of his class". So.... you see where this is going, right??
The next day I get a call from Rob at work, who is laughing. He was talking to the teacher who kept Colby after class FOR DETENTION the day before. It seems Mr. Chatterbox wouldn't shut up when he was asked, and him and a bunch of his friends were kept after school for it. So, me being me, had a bit of fun when Colby came home.
As Colby is walking through the door
"So bud, I forgot to ask, what was the math help yesterday for?"
Him, without missing a beat "The work we did that day. I didn't finish it so I stayed."
Me: "Colby, are you sure at this point you don't want to change your story?"
Him: "No, why?" (At this point he's starting to sweat a little bit)
Me: Colby, you know I'm a teacher right? You KNOW teachers talk and tell each other things, right?"
Him sheepishly: "You know, don't you Mom?"
The best part is the punishment for this. He assumed that he would lose his electronic privledges. OH NO. I told him he had to write a page on what really happened, why it's bad to lie, and what will happen if he lies again. I'm gonna frame it.
