Over and over

A: Boy, I'm glad that job is finished.

B: How long did it take?

A: Four hours, without a break.

B: It's always nice to finish a job.

A: Well, it's good and bad.

B: What's bad about it?

A: When you finish, all you do is start another job!

B: Yes, that's right. It does get boring.

A: Especially if it's the same work, over and over.

B: But that's what most people do.

A: Yes, I guess most of us are stuck in a routine.

B: I wonder if there is any job that you don't repeat over and over.
