That's fantastic, David! I am so glad that you were able to visit with your daughter. It's wonderful that she gets along so well with her roommate. My daughter got lucky in college, too,, and had a great roommate who she's still friends with.
I agree that it's very comforting to see your child doing well in their new environment. After my first visit to my daughter's college campus after she'd settled in, my worry for her decreased, too.
