This subject pinged a nearly-forgotten memory and I finally remembered it. When I was in my mid 20s I had a roommate, a very outgoing NT, who often seemed exasperated by me but was sometimes friendly. I forget why he brought this up but after several months he said, "You remind me of Tom Bombadil." (Tom is a great character in the first "Lord of the Rings" book, "The Fellowship of the Ring," who regrettably had to be left out of Peter Jackson's very, very, very long movies.) I was a major Tolkien nerd all through high school & the military but I couldn't even guess what this meant. Was this going to be a positive or a negative remark? - it was hard to tell with this guy!
He said, because Tom put the ring on and it didn't affect him at all. (Tom charms Frodo into letting him see the dreaded Ring, and shocks the hobbits by casually putting the Ring on his finger but he does NOT become invisible. He's the only character this happens to.) It's a cool analogy, that my roommate thought I was cheerfully (?), or more or less cheerfully, unconcerned & unaffected by the mundane obsessions of the NT world... something like that. Now that I remember that incident again, I'll try to keep it in mind in rough times!
