The thank-you thing had been drummed into us intensely when we were growing up. We had three great-aunts, on my mother's side, who believed that when they dropped a present in the mail, your thank-you note should essentially bounce right back out of the mailbox at them. If it didn't, the whole family, cousins and second cousins and all, knew about your lack of gratitude (and, come to think of it, common sense, as the threat was always that no more presents would be forthcoming, ever), and you heard about it from multiple sources. The notes couldn't be perfunctory, either--you had to put real elbow grease into them, writing something specific and convincing about each gift. So Christmas afternoon meant laboring over thank-you notes. As children, we hated this task, but when I saw Mom beam as she thanked people in the hospital, I realized something she had been trying to tell us all along. That there's great joy in thanking.
