On my way by train from Rome to Arezzo, I made the acquaintance of a priest who was reading and underlining passages in a book entitled Come Lui Ha Amato l'Eros di Gesu (How He Loved the Sexuality of Jesus). When drawing people I like to ask their permission first, and suggest they continue what they're doing without being distracted by me. In this case I didn't need to ask. The very friendly cleric never noticed what I was doing.
