Unfortunately, with all of the joking and sarcasm, the majority is correct here.

The hardest part is getting your foot in the door. Just because you're hired, doesn't mean you have a job, until 1 minute after your class date start time. Then at least you're on the seniority list.

The Mrs. must be accepting of the sacrifices of being on this job. The opposite is not always the case.

But don't let the doom & gloom get you down. Each has it's benefits at times too!
