Hello Sam, yes that's the way I remember the Dad and Dave words. Slow when a crises befell the family, faster in good times. I remember the Dad versus the 'roo picture too.
Speaking of 'roos I rather like the film "The Howling iv " subtitled "The Marsupials". It has a great birth scene where a woman delivers a baby and then keeps it in her pouch. Handy thing a pouch! I imagine. Joy
