Hi PaulS.
You are right again, what's it like being right all the time, my reading comprehension could be better, but i am not a teacher nor a full time student, as stated before i am a 70 year old Mechanical Engineer , with over 45 years of service in UK industry, you on the other hand are totally lacking in people skills, such as communication, as for your "la de dah" comment, how old are you 10, or maybe 12 ? the comments of a child.
If you do not like what I say and do, why do you bother to reply to my requests for help and assistance / guidance, you would surely get more satisfaction out of life, other than replying to la de dah old timers, like me, who don't understand your brand of the English language.
