So one night he dreamt that his mail carrier had actually approached him, saying "Hi, I'm from The Government and I'm here to help!" To which Ronnie readily responded, "Hey, I pay taxes which pay for your exceptional wages and benefits. So just do your job and don't come knocking expecting any cherries on top from me." Then he slams the door, cutting off the mail carriers response, "Uh no, Ronnie. I was just trying to inform you that your mailbox is smashed so badly that you'll have to go to the Post Office for your mail until it's repaired, but here's today's.. ah, fuck it, never mind then."
