Junior loves his grandmother. She has done so many things. Wise things. Kind things. She also very supportive of his choice to study at Reardan. His grandma died because a drunk driver killed her. Junior is right that when someone has lost a loved one then they will always act like a 5 year old. I would have felt the same. Gerald is the drunk driver. His grandma wanted them to forgive Gerald and her death.
She loved everyone
She is now gone
Everyone is sad
Now everyone is mad
Because Gerald ran over a loved one
