Today was the day Katie discovered that the refrigerator light does in fact turn off when the door is closed. I just found her intently sticking her nose in the fridge, opening and closing until she saw the little turn-off lever at the top. She had her "aha!" moment, then smiled, closed the door, and walked away.
"The light of the righteous rejoices, but the lamp of the wicked will be put out." Proverbs 13:9
