#1 Have you ever done,said, or thought something that you have regretted?
#2 Have you ever *not* done, said, etc... something that you have regretted?
For me, concerning #1, my biggest regret is allowing myself to say things out of anger,etc... and not meaning them. You know, saying "i hate you" because of anger, not thinking. You don't mean it, and you feel like a total arse afterwards.
Concerning #2, My biggest regret would be not following through in certain relationships. Letting my fear control me.
How about you?
