Oh, sorry, to answer your Qs:
Topics
~sleep patterns
~music
~pet peeves, top likes in shared living space
Call-back
~when you leave message, leave your e-mail address as well as your phone number
~if he doesn't return call, don't call him again. Maybe call a few days before school starts, be breezy about it, just checking in to see whether he wants to compare notes on who brings what.
In my case, there was no discussion necessary, b/c roomie's MOTHER stayed w/ us for a week to decide everything and go shopping with us to decide what we bought, who was to pay for what etc. She had guys from downstairs move my couch, decided one desk be used for household items and we share the other one, insisted we keep both beds in one room and so on.
