How do Tish and Fonny meet in Section One?

Tish and Fonny grew up across the street from one another, but they never really interacted until they got into a fight. Fonny's friend Daniel and Tish's friend Geneva started fighting and Tish and Fonny got involved. Tish grabbed the first thing she could, which happened to be a piece of wood with a nail in it and hit Fonny. Tish did not really mean to hurt him, but he started to bleed. She was sure that she killed him.
