A very depressed man

There's a man sitting at a bar just looking at his drink. He stays like that for half an hour. Then, a big trouble-making truck driver steps next to him, takes the drink from the guy, and just drinks it all down.The poor man starts crying. The truck driver says, "Come on man, I was just joking. Here, I'll buy you another drink. I just can't stand seeing a man crying.""No, it's not that. This day is the worst of my life. First, I fall asleep, and I'm late to my office. My boss, in an outrage, fires me. When I leave the building to my car, I found out it was stolen. The police say they can do nothing. I get a cab to return home and when I leave it, I remember I left my wallet and credit cards there. The cab driver just drives away. I go home and when I get there, I find my wife sleeping with the gardener. I leave home and come to this bar. And when I was thinking about putting an end to my life, you show up and drink my poison."
