I'm happy for you too. Something like that happened to me in a mall. I was walking along when someone from highschool came up to me and asked if I was my highschool name's sister, since I was a guy in school. I said I was the origional he knew in school with a few changes. My explaination of intersex became a seminar as a few curious people stopped to evesdrop.

As I learned, you are right not to flirt at first. Allow time for getting reaquainted. After ten years, you are different people in many ways. My friend and I still see each other, so who knows what could happen? Good luck!
