What is the author's tone in Toujours Provence by Peter Mayle?

Author Peter Mayle takes a light touch with his tribute piece to his adopted home located in the Provence region in the South of France. While he focuses on some oddities in French customs and some oddballs among the population, Mayle's humor is never acerbic or biting; rather, there is a genuine affection and good-natured wonderment that shines through. He uses irony and other rhetorical flourishes sparingly to enhance his non-fiction narrative.
