Miss Manners: Cousin and his wife fact

Dear Miss Manners: A cousin and his wife, who are close to me, have an annoying habit of click-clicking on their phones while we are talking.

I am about 20 years older than them. I have a background in the arts and culture, and was once known as a trivia whiz, which I don’t publicize. But this couple constantly fact-checks everything I say. And when they “correct” me, they are not always using accurate websites.
