Or he may be thinking I actually was calling s17, but wondering where the heck I was. Why I didn't need a car? And why wouldn't I know if s17 wasn't up? Wasn't I home to get them up?
I don't think he knows I carpool now, and I leave earlier than I used to. He must have been so confused. (Or didn't think twice.)
I think it's funny. Let him wonder. But no, I wouldn't clarify if asked. Just "Oops! My bad. Wrong number. Sorry!"
