At first, Dill tells Scout that his step-father locked him in the basement with chains, from which he escaped to the Finches' home. But later, after Jem has told Atticus of Dill's presence, Dill has eaten & bathed, & Dill and Scout are in bed, he tells her the actual truth.
"That wasn't it, he-they just wasn't interested in it me.
This was the weirdest reason for flight I had ever heard. "How come?"
"Well, they stayed gone all the time, and when they were home, even, they'd get off in a room by themselves."
"What'd they do in there?"
"Nothin', just sittin' and readin'-but they didn't want me with 'em."
So basically, Dill feels neglected and somewhat rejected by his mother and step-father. He goes on to say that they buy him anything he wants, but then tell him to play with it in another room. It also seems as though he doesn't live up to their expectations of how a boy should behave, because he's not really interested in sports, & instead hangs around the house "worryin' his folks." Dill feels they would be better off without him there, so he takes it upon himself to leave.
- Dill’s mom remarried and he doesn’t like them. They don’t pay any attention to him and just ignore him. His new dad said he would build a boat with him but he never did. His parents didn’t spend and time with him and they read by themselves in their room. They are always gone. He said they got him everything he wanted but they didn’t kiss him good night. He feels neglected because they don’t show any signs that they love him.
