There is nothing more challenging and essential in life than effectively navigating human relations.
No matter who you are, or how hard you try to avoid conflict, it's never 100% unavoidable. There are always going to be situations that will require you to speak up or to defend your position. Your job now, while understanding this, is to try to respond to difficult situations in a skillful and rationale way, so you can actually manage to get what you want, not simply express anger over an annoying situation.
When confronted with a loud roommate there are lots of things you can do to make the situation better. It is also very important to remember a roommate, by nature, is typically someone you can't get away from immediately; if you manage to get in a fight and make things awkward beyond repair you might end up shooting yourself in the foot.
1. Stay calm...
Even when you feel like exploding inside, getting super upset at them is probably not the best way to engage.
2. Try asking them to be quiet politely.
When it gets too loud for you in the room, ask for exactly what you want. ...
3. Rationally explain what bothers you and what you need.
Your roommate probably doesn't know he is noisy: noisy people don't usually know they are. ...
4. Keep reminding yourself... STAY CALM.
I SAID CALM!!!!
You'll be happy later, once you calm down and realize the reality of the situation, you'll remember that sugar is always better than a shit storm of poisonous venom.
