Petal, I've just read through your thread and Legend didn't pop up and make a snide remark.
You were throwing your dummy out of the pram because other AB members were mentioning him, how is that Legend's fault?
When Legend does eventually turn up, he was jovial and not spoiling for an argument, but it reads like you were and eventually Legend retaliates in the same manner in which you greeted his presence. He was even telling you that he was laughing and asking you to do the same.
I get why you're still angry with him, I read the thread a few weeks ago where you were picked on for, to the casual reader, nothing, and maybe Legend needs to think about apologising for that instance, however, you're stressing out ruining the fun of AB for yourself by getting so upset.
You can't make anyone stay out of a thread that you started, so maybe it's best if someone you don't like does post in it, to just ignore it?
