"I really enjoyed playing with building blocks as a child. I loved making tall towers and knocking them down. One time, after I had knocked down a tower, I got bored and went to ask my mom for permission to play outside. She said I could go out after I picked up the blocks I had left on the floor.

I went to my room, but when I walked in, I saw my younger brother, who was a few years younger than me, picking up the blocks for me. The lights were on, and he was very focused on what he was doing. I went and told my mom that my brother was cleaning up, and she looked at me, then glanced outside for a moment and said, 'Your brother is outside playing.'"
