I love college and I love you for sending me—I'm very, very happy, and so excited every moment of the time that I can scarcely sleep. You can't imagine how different it is from the John Grier Home. I never dreamed there was such a place in the world. I'm feeling sorry for everybody who isn't a girl and who can't come here; I am sure the college you attended when you were a boy couldn't have been so nice.
This is from Daddy-Long-Legs by Jean Webster. Why did she say such a rude thing "I am sure the college you attended when you were a boy couldn't have been so nice"? Why did she think so, though she doesn't know about him?
