I’ve read all the “essayettes” in Ross Gay’s “The Book of Delights.” I’ve cracked into Janice Kaplan’s “The Gratitude Diaries.” Gay’s “The Book of Delights” was surprising. I had to read all 102 entries before I had a good handle on what he meant when he identified a “delight.” They didn’t all seem delightful, at least at first. And Mr. Gay is a very different person than me. Some things that would have disturbed me didn’t seem to bother him at all. That’s sort of the point of me reading these books. I’m gaining new perspectives on gratitude. And I’ve a modest daily gratitude diary arriving this week.
