Answer:
Disappointed
Step-by-step explanation:
Sixteen is a short story written by Maureen Daly, an Irish-born American writer best known for the works she wrote while she was still in her teens. Sixteen is one of these works. She wrote it when she was sixteen years old.
The story tells about a girl who meets a boy at the skating rink and begins to like him. Before they part their ways, he tells her that he will call her. The excerpt you were given follows that part of the story. They met on Thursday, and on Tuesday, he still hasn't called. The narrator realizes that he will never call. She feels empty, disappointed. One part of her still hopes that he will call, but another has already accepted that he won't.
This is why the tone of the given passage can be described as disappointed.
