Catcher in the Rye- Chaper 24

Holden goes to Mr. Antolini's house. He welcomed right away. The apartment was a mess because the Antolinis had just had some friends over. Mrs. Antolini brought some coffee and cake into the living room for Holden and Mr. Antolini, then she went to bed. Holden was tired and wanted to sleep, but since Mr. Antolini was in a talkative mood, he listened anyway. Mr. Antolini was talking to Holden about being kicked out of another school and what he wanted to do with his life. He wrote something down and asked Holden to keep it. He says he still has it. Holden and Mr. Antolini get the couch ready for bed and Holden lays down. Mr. Antolini says he is going to stay up for a little while. He says he would be in the kitchen if Holden needed anything. Holden was awake for a short while before he fell asleep. All of a sudden Holden woke up to something on his head. Mr. Antolini was sitting on the floor next to the couch, petting Holden's head. Holden asked him what he was doing, but the only answer he got was "nothing." Holden was very uncomfortable with that situation. He got dressed in a hurry saying he had to go the station and get his bags. Mr. Antonini said Holden was to come back when he got his bags so hewould leave the door unlatched so he could come back.

What was going on? Mr. Antolini seemed like an okay guy, but then he became the scary guy everyone stays away from.
