Unfortunately I really do know the feeling... During schoolweeks I live in a house alongside 7 other students who are mostly completely unrelated.
The two sisters that live there argue a lot... I don't know them, but one of them lives in the room next door to mine and they always leave the door open so I hear everything they argue about and one of them always ends up crying... It's kind of weird having to pass that open door when they're busy fighting... Especially in the morning and all you want to do is go have a shower or something...
