Thanks for that, Tom. I've always enjoyed writing Granny. I think I'm influenced by those great Western lines I was talking about. I apologise for sounding vain but there was a Granny/Jesse James set-up I think worked well...
Granny at bar and and tough guy muscles in.
"Move it, Granny---I'm Jesse James."
"Son, you've got a big mouth and a girlie name---neither of which stops a knee in the groin."
Apologies again for the vanity but, dammit, I liked that!
