Also , I am very much a night person at cons and tend to come back to the room around 5 am . I will be quiet and respectful of those sleeping but this is a con and the only vacation I ' ve taken all summer and staying up till ungodly hours of the morning is just going to be standard . I also have friends who may or may not visit the room from time to time .

Question: Why may the narrator be trying to be quiet ?
Answer: None of the above choices .So as not blow their vacation .So as to leave the con with no one noticing .So as to compliment their social anxiety .
