What does Jeremy say about how his brothers treat T.J.?

From the text:

Jeremy stopped too. “I don’t know,” he said as if he was sorry he had mentioned it. “They just don’t do him right.”

Jeremy looked up at the sun, squinted, then glanced up his forest trail a few feet ahead. “They brung T.J. by the house a couple of times When Pa wasn’t home. They treated him almost friendly like, but when he left they laughed and talked ’bout him—called him names.”
