There was a guy in a bar, just looking at his drink. He stayed like that for half an hour. Then, this big trouble-making truck driver stepped up next to him, took the drink from the guy, and drank it all down.
The poor man started crying. The truck driver said, "Come on man, I was just joking. Here, I'll buy you another drink. I I just can't see a man crying."
"No, it's not that. This day is the worst of my life. First, I was late getting to my office. My boss was livid, and fired me. When I left the building to go to my car, I found out it was stolen. The police say they can do nothing. I got a cab to return home, and when I left it, I remembered I left my wallet and credit cards there. The cab driver just drove away. When I got home, I found my wife in bed with the gardener. I left home and came to this bar. And just when I was thinking about putting an end to my life, you show up and drink my poison."
Livid means very very angry.
If you're fired, it means your boss throws you out of the company.
Poison is something that will kill you if you eat or drink it
