What is the conflict of the story Bud, Not Buddy?

Remember that there are two major types of conflict:  internal and external. 

 To identify the conflict of a story you have to ask yourself about the major problem.  Is the problem within a character?  Is it a moral issue, or a confusion that the character has about some aspect of life?  If so, then it is an internal conflict within the character.

 If you identify the problem as something that exists between two characters, or between the character and his or her environment, then the conflict is external.

In Buddy's case, he is conflicted within, about his father, and he also has some minor conflicts along the way with other characters and circumstances.
