Since her retirement from teaching Miss Beryl's health had in many respects greatly improved, despite her advancing years. An eighth-grade classroom was an excellent place to snag whatever was in the air in the way of illness. Also depression, which, Miss Beryl believed, in conjunction with guilt, opened the door to illness. Miss Beryl didn't know any teachers who weren't habitually guilty and depressed--guilty they hadn't accomplished more with their students, depressed that very little more was possible.
