In Example 9-6, legally Hansen does not have to pay Everett a single penny, despite her promise to do so. However, is she ethically bound to keep her pledge and deliver to Everett the $35 that she promised to give her? Explain.

Data from example 9-6

Gale Hansen wanted to have her hair dyed before her college graduation party but could not afford to pay the $120 fee that was expected by the local hairdresser. Without any mention of payment, her friend Marianne Everett helped Hansen dye her hair. After seeing what a good job Everett did on her hair, Hansen told Everett that she’d give her $35 for helping. Hansen’s promise to Everett is not enforceable because Everett has already completed the work. Her consideration is therefore in the past.
