Explanation:
Mateo is speaking to the audience and refers to the audience as US indicating he is talking to fellow students about the injustice of the strict snow days.
Children are more likely to get bored listening to a talker with a professional tone or if the speaker is being more casual then the audience would think the speech is not important allowing the audience to miss the speech before it has even begun.
But by making the speech faster you are allowing the audience to begin to believe on their own about the injustice and it begins to work up their blood pressure.
Hitler was very good at getting the people to believe in what he wished because he made his speeches short and fast.
