How should I behave?

Two blogs in one day...I must be bored...

Actually the reason for this blog is because I'm confused. I'm now the mother of a college freshman. I've never been that before. I've been the daughter of one, the sister of one, the aunt of one, the...well, you get the picture! So my question is - how am I supposed to behave? What is considered acceptable? I know what I'm NOT supposed to do - things like showing up on her campus wearing Minnie Mouse ears and yelling "MY BABY, MY BABY." But what CAN I do? Will I be annoying Oldest Daughter if I call her? Should I just text her once a month? Should I only contact her if she receives a letter that she won the sweepstakes? Is it ok to ask her how her day went or if she is getting any sleep? I want to let her grow up, I want to give her freedom (ok, I'm just lying on both those, but I'M TRYING so that should count for something, right?). I want her to know I miss her. But I don't want to smother her (you notice the word mother is in smother...). Sigh. The things parenting books don't tell you!
