Seit er zu seiner Oma gezogen war, veränderte sich sein Körper. Ob es tatsächlich daran lag und er zu einem „richtigen Manne“ wuchs statt ein „hiefriger Knabe“ zu bleiben, wie sie es ausdrückte?

Since he had moved in with his grandmother, his body had changed. Was it really because of that, and did he grow into a "real man" instead of remaining a " scrawny boy," as she put it?
