funny joke

John was at a bar, just staring at his drink on the table.He kept staring at the ↽drink for quite some time.
Then, this 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 cant stand to see a man cry".
"No, it's not that... this day is the worst day of my life. first, i fall asleep, and i went late to my office. my boss outrageously, fires me. when i leave the building, to my car, i found out it was stolen. the police said that they can do nothing. i get a cab to return home, and when i leave it, i remembered i left my wallet and credit cards there.. the cap driver just drives away."
i go home, and when i get there, i find my wife in bed with the gardener. i left home, and come to this bar. And just when i was thinking about putting an end to my life, you show up and drank my poison.
