First off they were arguing for hours. I was kinda worried for my friend, because i hate arguments. but then i heard a thump on the wall and i knew my neighbor was attacking my friend so i go in their and threatened him so he'd get off my friend. he backed off immeadiatly, and my friend left to go get the authority. shit, it dipleases me when people yell when they are arguing, but when it goes physical, it pisses me off.
