You go somewhere looking for trouble you find trouble
As much as I want to say this is 100% true, it's not. I recently witnessed someone get jumped and not know who any of the people are. Never met or had an encounter a day in there lives. The dude was just bored and chose someone he didn't know to get it on with.
When liquor gets in people systems (particularly black) then tend to get touchy & extra sensitive about everything.
