Chris and Harris Have Been Friends All Their Lives

Chris and Harris have been friends all their lives. Harris has a successful dotcom business. He asks Chris, who works as a computer programmer at a large software company, if he could pass by that weekend to help him modernize his website. Working together proves very demanding on their relationship, with Harris throwing Chris out of his apartment when Chris has almost completed the job.

B) Yes, Harris should have expected to pay Chris for his services and the price should be a reasonable one.
C) No, Chris and Harris never intended to create legal relations.
D) No, Chris has not finished the entire job.
