🙂 my room mate moved to an appartment before school started (but according to the papers, which require freshmen to stay in the dorms first semester, he hadn't), so i had a dorm to myself for my first semester. next semester i'll probably be getting some random room mate.
i don't know what positive stuff there is to say about it besides the obvious. i've always been an independent and introverted person, so i may have a different take then you if you're more of an extrovert. but yeah, it's been great without a room mate, i've loved it.
as far as the negatives go,
just leave a door open and random kids will come to your room to hang out, it's not at all lonely.
i won't know for sure whether or not "room mate companionship" is anything worth wanting until i get one, but as i said, i haven't been lonely.
don't forget to slide the beds together, it's the tops.
don't know what else to say.
