Where I Tell My Son What's What

I'm in a carpool and and give rides to two of the neighbor girls. Yesterday, I think my son decided he wanted to play it cool and got sassy with me. If there's one thing I can't stand, it's when he's disrespectful to me in front of other people. I have no problem setting him straight even if it means embarrassing him. Witness:

Tyler: "One of the boys in my class told me he's kissed a girl."

[all three] "Eeewwww!"

Girl 1: "Oh yeah, I heard that from [another girl]. She told me he kissed one of his sister's friends."

Me: "What kind of kiss are we talking about? A peck on the cheek?"

Tyler: "I don't know. And mom? Mind your own business."

Oh. No. He. Did. Not! 

If I could have slammed on the brakes so I could turn all the way around and look him in the eye, I would have.

Me: "Get this straight, as long as you live at home and you're under the age of 18? Everything is my business. You have no secrets from me. Got it?"

At least he had the sense to look abashed when we pulled into the driveway.

What have you had to set your kids straight about lately?
