Anyone else have an annoying roommate problem?

I’ve been sharing this house with my best friend since 3rd grade and we’re about to start college soon. Don’t get me wrong, he IS my best friend, but he can be very annoying. For example, every time he gets something to eat, he ALWAYS comes in my room and eats. He doesn’t go in the kitchen or in his room. It doesn’t matter what I’m doing, whether I’m sleeping, making out with my gf, or jerking off. He always has to be in my room when he eats a meal. And he eats loud as f*ck and he constantly smacks his lips.
