I am not aware than any recent correspondent has been "taking the piss" out of me. I think most people around here know that that is a less than sensible ploy. And you clearly do not know what "erstwhile" means. It's a lovely word, but what a travesty it is when a tit such as yourself misuses it. Get a better dictionary, or, better, become better read. Better better better! Remember that from one of Paul's songs on Sgt Pepper?
