Nolan accepted a new job on the West Coast, necessitating a cross country move. He packed up a moving truck with his household goods one weekend and shipped them via a national truck service, but had to get to a meeting in San Francisco early on Monday morning, so hired Eric to drive his car from Baton Rouge to San Francisco the following week. Eric, who serves in the National Guard, was called to duty due to a hurricane, so recruited Theodore to drive the car to San Francisco. Somewhere in west Texas, Theodore hit debris, which caused a flat tire and complete destruction of the alloy wheel.

Can you describe the relationship between Eric and Theodore though the lens of business law in detail ?

Can you also describe the rights and duties among each party in detail ?
