Welcome to college. Most people live on shit sleeping and studying schedules and are very rude or simply have different habits. My roommate have figured it out, though our suite (we also share a bathroom with another room of 2 people) doesn't always since we have an alcoholic and a person with an incredibly odd sleep schedule (sleeps ~12pm-8 or 9pm and is awake all night and for morning classes/lunch). Shit happens–the year is almost over. Talk to him about it and if he is a dick at least you will have tried.
