Thanks Roger. You have not wasted your life as I see from your bio that you were a primary school teacher. Teaching children is the highest vocation as far as I'm concerned. Fascinated by your use of Tyke, which could mean "Yorkshireman" which you are, but as you down under it could mean Catholic, as Tyke is aussie NZ slang for catholic. In American tyke only means a little person. Usually a child.
