The night School ( for special adults) with miss Kinnian
Miss Kinnian believed Charlie was the best candidate for the operation because she recognized his strong desire to learn and improve himself. She saw his potential, despite his intellectual challenges, and felt that the operation could significantly enhance his life. Additionally, her personal connection with Charlie fueled her belief that he deserved the chance to experience a higher level of intelligence and the opportunities that come with it.
Ms. Kinnian knows that Frank and Joe are not Charlie's real friends because they make fun of him. Charlie doesn't understand that they are teasing him, he thinks they are his best friends.
The first book Charlie read with Mrs. Kinnian in "Flowers for Algernon" was "Robinson Crusoe" by Daniel Defoe. They used this book as part of their lessons to help improve Charlie's reading and comprehension skills.
She realizes a relationship with him would be unwise for many reasons, especially because he will soon revert to how he was originally. Therefore -- although the decision hurts her immensely -- she begins to avoid him.
