Both [of my granddaughters] Octavia and Lavinia have May birthdays. I've just been birthday shopping with them. But the shopping has a budget. I say, "Okay, if you pick this out, then you'll have how much left?" I wait for them to do the calculation, and they'll say, "$18." And we stand there and talk about, hmm, is that sweater really worth that much? And the girls work it through.Doing that takes away some of the magic of money.
