I agree, it's most likely just a curiousity/making plans thing. My first week of freshman year I was watching a movie w/ a guy and we both fell asleep (literally!) and I woke up to my panicked roommate calling my cell at 6AM to make sure I hadn't been kidnapped- I was planning on being home by 2. Also, I would ask if my roommate was going home for the weekend before inviting people over late, etc. because she was a very light sleeper and even studying together w/ quiet talking would keep her up. I'd say assume the best unless you have other reasons to think it's more than that. Oh, and about talking to the RA- most schools won't let you contact them directly because they'd be giving you their dorm room (basically home) phone numbers- that would mean that some overly concerned parent could call whenever they wanted! not that most parents would, but as a precaution. Your daughter will probably have to talk to the RA herself... which would be good anyway, since she's an adult now and should be able to start to handle her own problems.
