Chapter 23 - At the end of this chapter, why is it that Holden no longer cares if his parents find him at home?

Holden no longer cares if his parents find him at home because he didn't want to leave after chewing the fat with Phoebe. He wanted them to catch him so that way he could stay and although his parents would have been mad that he got kicked out of Pencey, he would at least be home now.
