I love telling vegetarians that I used to be one. You can see them start to think how I just must not have had the self-discipline and then I tell them “for fifteen years.” It is awkward because usually my “record” is double what theirs is and when they say “Oh, I know I’ll never eat meat again” I can tell them “I thought that, too, at year six”
For the record: became a vegetarian for animal rights reasons. Quit because it came to feel mostly symbolic
