I'm pretty hands-off, but I will say that I have sometimes said to my college kid: "Would you like me to take care of that financial/business thing for you? You seem pretty busy, and as long as I know what sorts of things you want, I'd be willing to serve as your secretary and make phone calls for you."
Heck, I don't even talk to my kid every day! I don't even talk to her every MONTH.
I'm always bemused by the parents I hear talking about their kid's college as if it's theirs. And they go buy the sweatshirt w/ the logo, and go to the games.
Our kid's college called us during their fund drive. I told the kid calling, "We give to *our* alma maters. When Grace graduates, she can decide whether she wants to give to hers."
Heck, I'm helping her pay an incredibly high tuition, so as far as I'm concerned, that's all the money I ever need to give them.
