My 3 year old lined up a tank, a fire truck, and a race car.
Abandoning the vehicles, he asked if he could get out the lincoln logs.
He needed help setting up a city. He's very particular about building. We spent a long time working together. I was gently but firmly corrected many times. He had a vision.
I went to get the mail. I pictured him playing "city" with little people. I came back.
I had missed the entire point of the set-up. The lined-up vehicles had not been abandoned. They were just waiting for a city to be built so it could be systematically and theatrically destroyed.
