Thanks Luna. I wouldn't mind if I had a clue what motivates these people - or even what planet they're on - but I don't, so if anyone here can throw some light on it, it would help enormously. Perhaps I deal with it wrongly. The problem is, if I ignore it, then it will be assumed that the 'idjits' are speaking the truth - and if I respond, they come back with even more nonsense - so what's the answer?
How would you (anyone) deal with it?
Starman, No, I didn't, but it's a good idea. I'll try it.
