I got a call from the dean of Carson's school last week. Turns out it was no big deal and she told me that right off the bat so I wouldn't freak out that maybe he'd done something stupid to get in trouble, like his dad did frequently. Like the time I made a pair of brass knuckles, (well, they were actually aluminum) in metals shop.
Maybe you get that call and you think "Uh oh, I forgot to pack her lunch!" or "Oh no, I gotta bring down a spare pair of pants!" Or "Oh No! HEAD LICE!"
Check out this great article from Parents.com, which I've subscribed to since Carson was little and I still get some good stuff off of here.
