I broke it with "I helped an orphan child to cross the street to get some food because they were afraid of the traffic."
All three responses were favorable. Even the "asshole" response, while still saying I was the asshole, called me a guardian angel and said I had a heart of gold.
It seems that way. I did a very simple one: "A car ran a stop sign in front of me and I flipped them the bird."
I got one NTA: "They shouldn't have run the stop sign!", and one YTA: "You shouldn't flip someone the bird just because they flipped you off, you should pull alongside them, assess the situation, and apologize if necessary."
