Jessica is very suggestible. We were driving down to the beach last weekend and she was complaining she was hot. Or cold. I forget. She's like Goldilocks that way.
Now, our van has an option where the back seats can either be controlled by the people sitting there or by the person in the front row. The person in the front row gets to decide who does the controlling. So I told Jessica how to manipulate the controls to make it colder/warmer with more/less air. She fiddled with the controls until she decided she was comfortable, and was very satisfied.
I didn't tell her the controls were set so I was the one doing the controlling and whatever she was doing didn't affect the temperature.
