This week's reading focused a good deal on the characters in story. They need to be identifiable from each other, and lit with uniquely believable personalities. Page 67 of the textbook really specifies the importance of the characters wanting something. They need a desire to drive their story.
Solanin really makes the story about what the characters and what they want. That's what makes this story so emotionally charged when it needs to make you feel something strong. This is a powerful scene where this character shares his empathy with his friend.
