After Mrs. Morrow met Holden on the train to New York (chapter 8) she rings up her son Ernest.

Mrs. Morrow. Ernest, love, how are you?

Ernest. Mom? is that you?

Mrs. M. Yes, of course, dear.

Ernest. (unnerved) Er … look, Mom, I don't have too much time. You know, I was on my way to the shower and all.

Mrs. M. That's okay. Just a minute or two, love. Listen. Guess who I met on the train yesterday!

Ernest. Mom, please …

Mrs. M. Rudolf Schmidt!

Ernest. Whaddaya mean, Rudolf Schmidt?

Mrs. M. Rudolf Schmidt, your classmate!

Ernest. Mom, are you kidding? Rudolf Schmidt is the janitor of our dorm.

Mrs. M. No, dear. I mean this Rudolf Schmidt who is in your class. A very nice, very polite boy.

Ernest. Mom, Rudolf Schmidt is about 100 years old or something. He can't possibly – wait a minute. What did he look like?

Mrs. M. Well, he was your age, of course. He had a Pencey sticker on one of his Gladstones, that's how we got to talking. He had a crewcut, and –

Ernest. Hold it, Mom! A crewcut?! Listen. Does he have sort of gray hair on one side of his head, by any remote chance?

Mrs. M. Yes, that's right, dear. That's him.

Ernest. Jesus! So – what did you do? Don't tell me you talked about me!

Mrs. M. Yes, we did. He was so polite. He only had nice things to say about you. In fact, he seems to adore you.

Ernest. Adore me?

Mrs. M. Yes, dear. He said you are one of the most popular boys at Pencey.

Ernest. He did?

Mrs. M. Yes. And he told me about the elections.

Ernest. Elections? What elections?

Mrs. M. He said you were too shy to accept a nomination for president of the class although everybody would have supported you. You should have told me about it yourself, dear. You know, mothers love to be proud of their sons.

Ernest. Yeah, I guess so. – Look, Mom, I really must take a shower now. Also, I still have a lot of homework to do.

Mrs. M. Of course, dear. One more thing: I have invited Rudolf to visit you in the summer. You two could play tennis and have fun. Wouldn't that be nice?

Ernest. Er – yes, that would be swell. Anyway, see you, Mom. Bye.

Mrs. M. Bye, love. And don't forget to let your towel dry after you've had your shower.
