Both my biggest regret and biggest achievement was convincing people I was a gay man turned trans-woman divorcee:

I still occasionally look at those two OP and laugh my ass off at the randomness of it. I honestly think I was at my best in those posts, better than I ever was.
But alas, my biggest regret was that I blew it. It was the only one time I broke character, and I regret it deeply. I could be a Trans divorcee woman now who broke his marriage of 8 years, over Steve who was feeding sushi to me with his chopsticks. And then begged my wife to take me back after transitioning into a woman, and tried to convince her that she had been in a lesbian relationship with me for 8 years with a legal document.
But I couldn't keep it up. It was just too much.
I guess I do have an identity, after all. Whatever part of me that finds all this funny must be the real me.
I regret it because I lost my credibility. People didn't believe the things about me that were true because I was basically Pinocchio who just demonstrated that everything Turncoat said about me was true... Such a shame. I wish I could take it back.
