what do you learn from Dill's account of his running away?

Dill tends to exagerate when he tells a story,

Having been bound in chains and left to die in the basement (there were basements in Meridian) by his new father, who disliked him, and secretly kept alive on raw field peas by a passing farmer who heard his cries for help (the good man poked a bushel pod by pod through the ventilator), Dill worked himself free by pulling the chains from the wall. Still in wrist manacles, he wandered two miles out of Meridian where he discovered a small animal show and was immediately engaged to wash the camel. He traveled with the show all over Mississippi until his infallible sense of direction told him he was in Abbott County, Alabama, just across the river from Maycomb. He walked the rest of the way. ch 14

We know that Dill just was not getting the love and attention that he received in Maycomb.
