I wonder whether I would have had such an impetuous response if I had said I agreed with you, of course that would have been a much more valuable contribution to the content of this thread. I apologise in advance for the waste of space my posts have taken from other much more substantial ones. I personally don't feel the need to elaborate the reasons why I agree with NSF but since you showed interest, I will. In essence I appreciate his positive attitude and willingness to make things right/better and not spending days in misery and wishing you were somewhere else where the grass is 'obviously' always greener.
