Two men, both seriously ill, occupied the same hospital room. One man called Ben was allowed to sit up in his bed for an hour each afternoon to help drain the fluid from his lungs. His bed was next to the room's only window. The other man, Leo, had to spend all his time flat on his back.
The men talked for hours on end. They spoke of their wives and families, their homes, their jobs, their involvement in the military service, where they had been on vacation.
And every afternoon when Ben could sit up, he would pass the time by describing to his roommate all the things he could see outside the window. Leo began to live for those one-hour periods where his world would be broadened and lightened by all the activity and color of the world outside.
The window overlooked a park with a lovely lake. Ducks and swans played on the water while children sailed their model boats. Young lovers walked arm in arm among flowers of every color of the rainbow. Grand old trees graced the landscape, and a fine view of the city could be seen in the distance. As Ben described all this in detail, Leo would close his eyes and imagine the beautiful scene.
One warm afternoon Ben described a parade passing by. Although Leo
couldn't hear the band — he could see it in his mind's eye as the gentleman by the
window described it with descriptive words. Each time the nurse saw the warm and
touching scene 
she was always struck by devoted friendship between these two men. Days and weeks passed.
