Upon returning from Walmart with the kids, I watched them do a happy dance through the front door, pry our bags open and spin about the house with their newest prized possessions. I realized what I love most about this age is that the simplest things make them positively euphoric: $1 plastic bowls with built-in straws, Dora electric toothbrushes, brand new Thomas the Train underpants. How many more Christmases do I have left before they realize Santa’s a tightwad?
