Final answer:
Maya is upset on Halloween night because her friends were lost at the party.
Step-by-step explanation:
Based on the given information, we can infer that Maya is upset on Halloween night because her friends were lost at the party. The passage states that three boys called, and Marjorie disappeared with one of them, while Bernice tried but was unsuccessful in entertaining the other two. When Marjorie enters Bernice's room later, she apologizes for forgetting about the Deyo dance, suggesting that Maya's friends left her to go to the dance without her.
