They met at a dance, where he walked her home. The next day, she invited him for dinner at her parents' house (she was only 17). That was a Sunday evening, and later that night, he shipped out for England.
They never wrote or communicated in any way in the two years he was gone.
He returned to Canada, and instead of staying on the train to his home in Vancouver, he got off in Calgary and caught the train North to Edmonton. He walked from the train station to her house, and invited her for a stroll downtown. As they did, a street photographer took their picture - the one you see here - and my Dad agreed to buy it from him.
What you don't see is the ring in his pocket. He is about an hour away from asking her to marry him.
She will say "yes".
