K, here goes again!
In early 1939, my mother's father went to a dance hall one Friday night for the usual ballroom/big band evening.
He was one of 15 children, and they certainly weren't the minted type.
He looked across the hall, and there was his sister Delia talking to a woman in a cherry print dress.
He couldn't keep his eyes off her.
His mates were all nattering away. Then he said, 'See that lady in the cherry print dress talking to Delia?' They: Yeah, so? He said, 'Well, I'm going to marry her.' They all started laughing and chiding. He said, 'Excuse me, gentlemen, I'm going to go ask my wife to dance.'
And he crossed the hall.
The woman in the cherry print had come over from France just a few months before to tutor the children in the big house where his sister worked as a maid in French.
He got his introduction, and his dance.
He was the eldest of a total of 9 sisters and believe you me, to dance with him was like floating along on air, he was so light of foot you barely felt his lead.
She said he asked her for a dance and from the second she stepped onto the floor with him she knew, too.
Three months later, they were married.
He died 44 years later of a heart attack.
Again, they didn't have kids before they met.
But there you go.
It can happen.
