This morning the youngest came downstairs to see what St. Nick left in her stocking. She looked at all three like she was sizing them up to choose the best one, and settled on the one on the left.
"How do you know that one is yours?" I asked.
"Because you always line things up oldest to youngest or youngest to oldest. I looked in the one on the right and it was empty except a few candies so I guessed that was the one St. Nick sent to my sister at college, which means the one on the left is mine."
Apparently St. Nick has the same OCD issues as me - who knew?
