Blood, there are probably very few who post on this board who haven't had an upper and downer with someone else, I know I've had a couple, but it's best to just laugh at their ignorance, if they are wrong, and agree laughingly, than to feed them with anything that will continue the argument, which can get totally out of hand. It can be very frustrating for someone reading the posts to keep coming up against a row between two posters which continues fo more than a couple of posts. If I've upset anyone with my comments on the matter I apologise, it was complete frustration on my part. I'm sure you will enjoy the book, albeit a precis of what went on. No one is perfect, myself included.
