As my wife prepared dinner the kitchen filled with smoke, and the smoke detector went off.
Although both of my children had received fire safety training at school, they did not respond to the alarm.
Annoyed, I stormed through the house in search of them. I found them in the bathroom, washing their hands. Over the loud ringing of the alarm, I asked them to identify the sound.
"It’s the smoke detector," they replied in unison.
"Do you know what that sound means?" I demanded.
"Sure," my oldest replied. "Dinner’s ready.”
