<human>: Can you provide a brief overview of the text?

As a naturally socially incompetent person, awkward situations happen to me pretty often. When I'm drunk and bored though, I become an embarrassment to humanity. After a concert last night, my friends and I went out bar hopping. On the way to the next bar, I spotted a man with a guitar just strumming away. I noticed a hat on the ground which I assumed was his. So thinking I was being a good guy, I put his hat on his head (a normal person might have simply tried to hand it to him, but i'm a lost cause for normalcy). The guy gave me the dirtiest yet confused look on his face. The next thing I know, my friends just keep calling me an asshole. "That hobo did nothing to you, man."
<bot>: I placed a panhandler hat with money in it on a homeless man's head because I'm a terrible excuse for a human.
