-- Now you have hired a female student to be your mistress, how do you feel?
-- It's so boring, I regret it so much. I am an adult and she is a child. I can see right through her, but she can't understand me at all. She needs my help and support, but she has no help for me. She has to endure her self-righteousness, rebellion, paranoia, and persecution paranoia as a young person. This is purely a one-way communication, and it is better to be with people of the same age.
-- If you can see it this way, it means you are still young. When you can really tolerate young people, you will be old.
