One day - I remember it was a Sabbath afternoon - I came to the synagogue with a book in my hand. I saw a commentary on the Bible by a certain Rabbi Moshe Dessauer, better known as Moses Mendelssohn. An elderly man came up to me - I was then maybe 10 or 12. "What are you studying?" he said. "Dessauer's commentaries," I said. So he gave me a slap on my face.
