The reason why people think you did this for attention is because we've seen it SO many times before. People would always make a thread, saying that they're leaving and then come back, like, a week later. I can say this because I did the exact same thing.
I can sense, though, that you really did mean to say goodbye. Obviously, you seeked SOME attention. Otherwise, the thread would have never been created. But I think some people(yes, Gerry, as much as I want you to bear my children, i'm looking at you) were just a tad bit harsh.
I'm not in any position to forgive you or not, i'm just offering my two cents.
