Just had to smile at the bingo analogy, EC1. It's spot on.
My maw started going to bingo relatively late in life as she sought a way out of the drudgery my father was dragging her into. She went with his sisters and came back saying exactly the same thing as you: why are they unhappy when someone wins? Why aren't they happy for them? Why are they angry that they were only waiting for one number? I loved my aunties and thought they were wonderful wee wimmin but seeing my mother's reaction made me think.
