Eyes to eyes

The old man in the store as I was buying today's newspapers. He never once raised his head. Never once looked at any of the people at his cash register.
He looks old, probably more than 70 years old. Working on a Saturday at the check-out register of a supermarket. I wonder what the story of his life is. Why is he here. Why he does not meet the eyes of his costumers. Why his face looks so sad and beaten. The face of a grey raining day.
