A man with a gray beard and a little boy are sitting on the floor looking over some papers in a room with a bunk bed.
The man is reading to his grandson.
The paper may not have words to read, and the man may not be related to the little boy, so this does not signify the man is reading to his grandson.
We have no idea if he is reading, because he is holding paperwork doesn't mean he is reading. We have no idea if the boy is his grandson, it could be anyone.
Just because a man is sitting with a little boy and looking at papers does not mean he is reading to his grandson.
