why is travis getting so little sleep ?

Travis is getting so little sleep because his father and his father's friends are talking in his bedroom with all of the lights on (he sleeps on the couch).

"Oh, no he ain't going to be getting up no earlier no such thing! It ain't his fault that he can't get to bed no earlier nights 'cause he got a bunch of crazy good-for-nothing clowns sitting up running their mouths in what is supposed to be his bed-

room after ten o'clock at night . . . "
