What is one "unwritten rule" you think everyone should know and follow?

I had a couple roommates who wouldn't turn their games down past midnight when they knew I got up at six in the morning. Three o'clock rolls around, there's this huge boom from the game, I get up, come out in a pair of sweatpants, sit down right beside them and shout in the most sarcastic tone I could while staring at them, "I GUESS THREE HOURS OF SLEEP IS ENOUGH"

They utter a very condescending reply of "You could have just asked us to turn it down".

No. I could not. Because you knew I had to get up in the morning. Because I already did. Because I have to skewer you in order for you to learn. You're lucky I didn't throw that fucking console put the window and into the highway.
