Answer:
The answer is: Reed's promise is not enforceable because he is a minor.
Step-by-step explanation:
Minors (people under 18 years of age) are not allowed to participate in any kind of contract except for essential items like medicine or food.
In order for a promise to be enforceable, Reed's parents must give prior consent. Only if Reed was an emancipated minor would he be able to make contracts or legal promises, but apparently this isn't the case.
