Something to watch out for

I was waiting to pick Ethan up from school today and Micah and I were standing by the wall while we waited for Ethan's class to finish. As usual, Micah was chatting to me about his surroundings. He looked at the wall, reached over and pointed. "Light" he said. No, Micah, that is not a lightswitch. That is the fire alarm. Why do I feel like he'll pull it someday?
