The narrator tells us that today is the birthday of a friend he used to care about. After that, things got worse for her because of him. She tried to embrace people no matter how hard they tried, so she started to doubt that she was making the right choice. The narrator says that if she had asked him for help, he would have been there for her even if she was having a hard day. He admits that he was foolish, not her, and that she sank down to the depths of the abyss.
