Dad, tell me more about engines....
We're driving home from visiting my cousin and his family. The kids and I stayed there for a whole week. It was a blast. Now we're on our way home. Gratton asked David how cars work, and how you make them go faster. David explained pistons and stuff, and asked if he understood. Gratton said yeah, I understand. Then he had his thinking face on for a while, and said- "Dad. Tell me more about engines." It's really cool how Gratton is so curious and wants to learn about everything.
