I explained the economic downturn to my son, who is 9, in terms he could understand. “It’s like we’ve done something bad, so the whole economy has to go to its room and think about what it did and what it can do differently. We’re in our room, alone and sad right now.” He bought it, and unlike some of the things I explain to him I eventually bought it, too. The problem, of course, is what we tell the great economic parent when we come out.
