My dad is called Bill and my Grandmother lived in the North East. When I was younger and it was getting cloudy and dark my mum would say "Aaaaaay lass. It's black over Bill's mother's." I always thought that my mum was super human and could see all the way across the country. For a time, I always worried that mum could see what we were up to when we were playing away from home. Never found out what it meant. Sorry.
