Morrie says "Love each other or perish." (Albom 149)
This chapter talks about the "rules" of marriage and what makes a good relationship work. This chapter also talks about Morrie's relationship with his wife and what are the things you have to keep in mind if you want to have a successful marriage.
Morrie teaches Mitch that he needs to put effort into his relationship to make it work. He also teaches Mitch some basic "rules" to help their marriage.
One symbol from the chapter is when Mitch's wife Janine starts singing and Morrie starts crying. This is a symbol because Morrie learned how to enjoy the little things in life with his wife.
