Nowhere....
I too cannot believe that you have ever intentionally hurt anyone, at least not here. I have read your posts, and even in the most difficult situations you have been able to keep your composure. Because of that, many situations have been defused, that in the past may have ended up in a locked thread.
I think you have more patience with people, at least at this site, than I ever will. But because of you, I try harder to practice patience.
Because of you I try very hard to post from my intellectual mind as opposed to my emotional mind. That might be easy for some people, but not me

, and believe me sometimes that takes a heck of a lot of work........but your worth it

.
If in fact you have hurt someone here, then I can't think of anyone who deserves forgiveness more than you.
Please take care of yourself!
