So Considerate and Thoughtful

Our house has only one bathroom on the main floor.  This evening, as I was TRYING to do something with my hair, my youngest son came in. 

"Mom, I need to wash my hands." He said.  He eyed the straightener that I had in my hand, plugged in right next to the sink.  "I won't electrocute you if I turn on the water, will I?"  He asked.

I checked, just to make sure that the cord hadn't slipped into the sink unnoticed by me.

"No.  It's fine.  Go ahead and wash your hands."

"Well, if I do...I'm sorry."  He said, matter-of-factly, as he turned on the water.
