Rich should have called. Gary would have been more than happy to go and pick him up and escape the madness of the airport for Rich and the madness of our house for Gary. I'm sure they could have found some place to pass the time.
I'm wondering if Nick has a case of puppy love as well?

Being he's spending his days talking to the girl next to him in class. Maybe you could suggest to the teacher to put him next to the most quiet kid in class, one who won't talk back to him? Maybe he'll get bored and focus a little better on his schoolwork?
I also think a visit to the principals office might not be a bad idea so the principal can help Nick get his priorities back on track.
Our school has something called "lunch club". I think it's only designed for kids who don't do their homework - instead of going out for recess, they go to lunch club so that they can complete their assignments. Walker tells me that it's sometimes used to write a punishment. Does Nick's school do anything comperable?
I'm sorry your having a tough time of it.
