when I leave a place I like to know I’m leaving it. If you don’t, you feel even worse.” What does this quotation show about Holden’s character?

This quote has to do with Holden's inability to connect to people. He's actually saying that he's sad..... that he isn't sad. Leaving somewhere usually means you feel bad over who or what you're leaving behind. Holden didn't have these feelings.... and it saddened him.
