Chapter 20-22 - Explain what Holden may mean when he describes his sister as "quite affectionate" for a child.

What i believe Holden means when he says that Phoebe is "quite affectionate" for a child is that normally children don't show a lot of affection to others because they are unsure of how to or just don't want to, but Phoebe is different when she seen Holden she was very happy and hugged him. Phoebe shows affection like other children really don't.
