Sticking to Our Letter

Every Friday night, a man in prison hears name after name called out at mail time, and his own is called again and again. A prisoner next to him is furious. What does Rabbi Asaf Prisman take from that scene for the days before Yom Kippur? Parshas Vayelech starts with a mitzvah that seems redundant: even a man who inherits his father's sefer Torah must write his own. Why, and what does the Ksav Sofer say about doing mitzvos out of habit? It raises a question for anyone who simply follows the way they were raised.
