I have a question.
Was school out the next day? If the weather was in fact as treacherous as you state, and it was evening time.... then you would've already known that the schools were closed. My guess is you live in NoVa, and I *know* VA posts these things on the news right away.
My point is, that the argument about missing school isn't valid if the weather was already so bad. In VA, kids don't go to school when there are even a few flakes on the ground.
Now, unfortunately, I do see this as a control issue for BOTH of you.
