# Review and Reflect
# So I misunderstood the challenge before this and assumed we were supposed to make
# an object. In this instance it just seemed more reasonable to make this an object 
# from the beginning. Although objects do require some extra code, it makes it easier
# to organize and add methods to an object, or reuse methods in another object.
