We're back in Madison after a couple of non-eventful flights—my favorite kind. I'm looking forward to seeing my mom and friends and enjoying our home here, which now seems immense after our casita in Costa Rica. First, I have to get through the annual reverse culture shock. (After I get over the fact that this cool rainy spring day is colder than what they call winter in Costa Rica.) I have many common reactions to being back in the U.S. including how big people are—I'm no longer a giant among men. But most of my culture shock happens at the grocery store.
