You don't know how much I relate to this. Mine is on a smaller scale, but I've come to realize how different people are from myself, and I still don't know if I can accept it or simply endure.

I stay at the college dorms and I just see these things play out in diverse ways, and I'm like, "It's okay to be free and do what you want, but why can't you just take a moment to consider the impact of your actions on the next person."

It's not that deep and no one is asking you to constantly put people's needs above yours. Like you said, it's just basic courtesy. I said I'd come back tired from lectures and just needed to sleep off a bit. But you'd make insanely loud calls, cackling all night in the room for four hours straight. It's really sad. Sorry about the poor lady. Hope she can one day move or maybe he moves.
