There is an interminable rain at the 4077th and everyone is feeling claustrophobic. When mail call comes, there is a package for Hawkeye. It is from a fourth grade teacher in his home town. She has asked the kids to writer to the crew, either a doctor or a nurse. Hawkeye, instead of answering them all himself, gives a few to each of his friends. The episode then is formed from their responses to the kids. Some are silly; some are charming. One really gets to Hawkeye, however, as it is from a kid who blames all doctors for patching up his brother and sending him back to the front where he was killed. The letters are all touching in their own way. Potter tries to set the camp record for the most consecutive free throws. It's a nice study of how these people met each day head on.
