Over the years I've been writing a series kind of on the side. I write little short stories about all the characters when I'm stuck on other projects, starring a blue-collar family of six living in Illinois. Anyway, the mother's oldest son has just started college, and she discovers he's tried smoking pot while there, but she can't think of any way to punish him for this as he doesn't live with them anymore, is 18 and they aren't even paying for his college. I can't think of anything either... It can be both serious and humorous. Help me out a bit here It would have been easier if it wasn't already established that the son isn't easily embarrassed.
