Memorandums are important because Memos have a twofold purpose: they bring attention to problems and they solve problems. They accomplish their goals by informing the reader about new information like policy changes, price increases, or by persuading the reader to take an action, such as attend a meeting, or change a current production procedure.
Moana both involves going to sea and going against the advice of others, while it differs because Moana is *literally* a teenage girl, unlike Odysseus.
