Johnny lives in a single parent environment. Johnny has four hours after school before mom arrives home from work. Johnny wants to be a carpenter. Right down the street, we have Frank. Frank is a retired carpenter, who lives in an assisted living center, along with the memories of his past.
Nobody knows they have something to offer one another.
A communication link between the two does not exist. Perhaps Johnny would get excited about learning and gain 'real world' knowledge from someone with past experiences. Maybe he could fill the gap by learning work ethics from someone who is there for him. Perhaps Frank could liven up his life through the eyes of a young person. He may learn more about computers, the internet, and our modern world.
