I met two men who graduated from the same high school in the same year even though one was two years older than the other. One man had enlisted in the navy and gone off to fight battles. After the fighting ended, he returned to high school. Only because of a war, did they become classmates. Once graduated, they went on to lead separate lives.
I met them a week after they had been unintentionally, accidentally reunited in a nursing home. It had been twenty years since they last saw one another Both are in their eighties, roommates for a while. Two experiences shared, sixty years apart, positioned them for friendship.
How much will they share of the in-between? My guess is that each day will be back to the future.
