But, instead of complaining about why I hate my job tonight, I'll tell you a joke that sums it all up.

A mother goes and wakes her son up on the first day of school.
"It's time to get up for school!" she says brightly.
"I don't like school and I don't want to go," he responds.
"Well, why don't you like school?"
"The teachers hate me.  The kids hate me.  And, I think the lunch lady is trying to poison me."
"Well, you still have to go to school."
"I hate school and they hate me.  Why do I have to go?"
"Well, because you're the principal."
