damn, he better be ok. i absolutely hate unprovoked aggression like that.
last summer i had a similar thing happen but less serious. in the middle of the night some loud crazy fucker banged on my neighbor's and/or my door (not entirely sure). he was screaming how he wants to fight everyone and how he hates the city and other random threats. dude sounded like he was losing it, really desperate. the next morning i found a chair smashed to pieces right outside my door.
fucking selfish aggressive pricks, learn to deal with your problems without attacking others. you're not the only ones with issues... just let us sleep in peace in our own homes. assholes.
