Two jobs

This evening we were out on date night. When we got back we checked to see how things went with Joy and she told us a funny story. This summer at UT she is taking anatomy and physiology - two killer courses in six weeks. Vivian asked her what she was studying. Joy explained that it's stuff about the human body. Why? Because doctors and nurses need to know how the body works and what to do to fix problems, Joy replied. But you aren't a nurse or a doctor. Joy explained that she hoped to be one someday. Vivian said that then Joy would have two jobs. Joy was confused and asked what her other job would be.

"You will be my babysitter too. I'll need a babysitter when I'm in high school and college because I'll still be little."
