Books David Sedaris on Duolingo, death, and dressing like a priest With a new collection of essays under his belt, the acclaimed humorist started his ‘Lobster Roll Tour’ through New England this week. We talked Duolingo, death, dressing like a priest, and the power of third wheels. David Sedaris: About four years ago, my friend Dave introduced me to Duolingo, and I got addicted to the games. I didn’t know I was going to write about it until I got that email. But I don’t wear the collar with it, because then you have to worry people are going to approach you.
