At some point in your life, you'll probably find yourself sharing a room with a sibling, a fellow prisoner, or a hamster that's honestly more like a prisoner. Here are some tips for peacefully sharing your space:

Compatibility: If you're going to live with someone, you two need to agree on major issues, such as how many bathrooms should have refrigerators and whether or not to raise a child together.

Decor: Hang up quotations from poets and photography of nude animals. If your roommate likes this decor, move out.

Chores: Take turns washing the dishes, cleaning the ceiling, and eating all of the garbage.

Boundaries: You don't want your roommate touching your stuff, eating your food, or sneezing in your terrarium. Make it clear which side of the room is yours by coating it in the ashes of your last roommate's shirts.
