We have a wall fan in the living room. When we set out floor mats for workouts, we often asked Calder to rotate the fan towards those mats. But he didn't know how to control the remote control to point the fan in the right direction. So we prompted him. One day, I realised that he didn't need our prompting anymore - he knew when to press the button to stop the fan's rotation. Today, when I asked him to turn on the wall fan, he proceeded not only to turn on the fan but to rotate it slightly to the left (using the remote control) to blow at where we were seated. Wow.
Thank God for little breakthroughs!
