Thanks Shysal for explaining to me what I was missing.
Yes I have rather thrown myself into GN as you say. I keep coming up with questions I would like answering, hence I am putting on at least three new threads a week, if not more !
I loved listening to The Navy Lark and Round The Horn with my darling father last year, lovely memories of our time together both as a child and in our 'older years'. I can see him now having a wry smile, the difference being when I was younger I would laugh because he did but I didn't have a clue what I was laughing at.
