Well, Archer just graduated from the same preschool, and at the party on Saturday he was the one to win a Swedish fish in a mock fishing game only for the new grads. At once, and without a word, he brought it over to Jonah, tore it in half, and shared.
I was stunned — even more so when Archer informed me that he shared because he remembered (despite being three at the time!) Jonah doing the same for him.
