Holden's relationship to Phoebe

Phoebe is Holden's sister. He loves her sister very much except when Holden behaves in a very mean manner when Phoebe cries and has a fit. Holden cherishes Phoebe a lot because she is the closest relative Holden can connect to. Holden tries to connect to her by expressing his feelings, what he has gone through and how he thinks the real world is a phony. Whenever Holden spoke of Ally, he also spoke of Phoebe always wanting to be like them. Another reason why Holden cherishes Phoebe is because she thinks so highly of him.
