Opposable thumbs that oppose the body they're on.... poor little granddaughter and thank heaven for modern medicine! Not that long ago, mothers and witches were blamed for "birth defects." Genetic anomaly sounds nicer... thank you for the kind words! BTW, the more we write, the more inspiration strikes. It's like if you never exert yourself by opening the window, you'll never let the sun in. Or something like that. I love your writing!
