okay, so we all know certain individuals get some sick pleasure out of riling others, so why not just stop playing their games? yes, it's sick, sad etc. we all know that.
but surely it's best to just not respond.. after all, they want your attention and that's what they always seem to get. it's sad, attention seeking, and we don't reward bad behaviour, do we??!
it needs one brief response (like a full stop) to remove it from the "unanswered questions", and that's all.
