It may have come to no surprise that I have fuax pas'd on a thread using a jokey analogy that has annoyed crablin/ in incolved people with beards and I used him as an example with no 'harm intended' and as usual i've been misunderstood. Sorry to all parties, even though the joke wasn't sick or nasty. I just didn't 'point out' that is was 'in good humour. Oh dear.
