Ahh well ...

There's this little guy sitting inside a bar, just looking at his drink.
He stays like that for half-an-hour.

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 can't stand to see
a man crying."

"No, it's not that. Today is the worst day of my life. First, I
overslept and was late to an important meeting. My boss, outrageous,
fired me.

When I left the building to go my car, I found out it was stolen. The
police, said they could do nothing. I got a cab to go home, and after I paid
the cab driver and the cab had gone, I found that I left my wallet in the cab.
I got home only to find my wife with the gardener. I left home
and came to this bar. And when I was thinking about putting an end to
my life, you show up and drink my poison ..."
