Grandma's job

The other day, Faith and I were walking toward home from the high school with Jason's parents, since they live just 2 houses down.  Mom is a construction manager for a business that will be working on the school this summer.  I asked her when they will get started and we were talking about it.  Faith then asked her, "Grandma, what do you do?"  She explained to Faith, "Well, I set up bids for commercial buildings, write up estimates, and if we get the bid, I oversee the contractors and organize the scheduling and keep the project moving forward."  (That might not be what she said word-for-word, but the point is that she went on explaining in great detail all that she does as a construction manager.)  After all that, Faith replied, "So Grandma, you make commercials??"  I'm still laughing.
