Robot Camp

The boys are in Robot Camp this week at the university. They're having fun programing their robots to dance and move in patterns.
Today we went out to lunch. Behind the boys is Mary's office.
All week they wanted to go back to a lecture hall to give a talk. You won't believe what the topic was...
I sat patiently and listened. The lecture was far longer than anticipated.
When referring to the lecture hall, Jack kept calling it "The Stadium."
