No real update, but I did tell my DD to read your responses, which made her feel better. Since classes start tomorrow, there are other things on her mind so she is not broaching the subject yet but hopes to do so soon.
The roommate has offered to share clothes (she wears size 0 and m DD wears 2's) and her vast costume collection (they have events in their sororities that call for costumes.) My DD is not interested in her stuff. She really hasn't expected the RM to share anything, just not demand to use her stuff!
My DD brought her TV (a free one neighbors gave us). The college provides the microfridge, so there really isn't anything else needed. That's ok with me.
DD had a mini-freak-out when she first hooked up her printer this evening. Apparently her computer was searching for the wireless computer here at home about 300 miles away!

I was afraid it was karma! Once she instructed her computer to connect to the one in her room, she DID get it working and the fear of it NOT working made her even more sure she doesn't want to share it. She had to print a syllabus for her first class tomorrow and couldn't imagine not being prepared. The library would be closed when she would be able to go to it.
I will update if/when there is anything worth mentioning, but I want to say thanks for providing feedback since I was so taken aback by the reaction to our not wanting her to share it, except for an emergency. I wondered if I was missing the boat. Apparently from your responses, I am not crazy!
