what kind of person does the coat incident show t.j. to be?would you want him as a friend?why or why not?

When Mama asks for Stacey's coat to shorten the sleeves, he has to admit that he has lent it to TJ until he grows into it. TJ was making fun of him, calling him preacher because of the way the coat fit. Mama wants him to get it back, but Uncle Hammer tells Stacey that if he is stupid enough to give his coat away, then TJ can keep it permanently; Stacey will not survive in the world if he lets people take things from him. T.J reinforces the fact that he is selfish and manipulative to those that care about him.
