What would you change in the book Bud, Not Buddy?

In order to give Bud's story more closure, I would have allowed Bud to meet his father. I love the idea that Herman E. Calloway is Bud’s grandfather. I would not change that.

This is truly an opinion question; therefore, it is important that you figure out your own opinion on what you would change. However, I am happy to add my ideas on the subject. In order to give Bud's story more closure, I would have allowed Bud to meet his father. I love the idea that Herman E. Calloway is Bud’s grandfather. I would not change that. However, it would have been an interesting idea if Bud’s dad was actually a member of the band. Maybe Herman E. Calloway could have been inclined towards Bud from the beginning while Bud’s dad could have been a gruff and calloused member of the band who would have nothing to do with Bud. Perhaps the revelation would come at the end of the book, giving Bud's story the ultimate closure. Further, because Bud “no longer knows how to cry” until he finds his “home” with the band, perhaps the “rusty old valve” could open for Bud to cry during the reunification of Bud with his real father.
