"I'm with you. Mine is living at home and I still worry about her. She has night classes and a 30-40 minutes drive. I have her call when she leaves school. It used to be "aw Mom." Now it's just a resigned "ok" to keep the mama happy."
I so know where you're coming from. I could have written your post. It's good to know that I'm not the only mom out there who does the "call when you leave" thing :)
Every once in a while, I meet a mom who says what you do. If my daughter is at the function with me, I drag her over and make them repeat it. She just hates this stuff. I tell her that's ok, that she had just better do it for my granddaughter (should God bless me with one... or two... or three... or... ok, I won't push it)!
