Alice in Wonderland: Chapter 9 & 10

When Alice meets the Mock Turtle with the Gryphon,they talk about a teacher who was called the Classical master, who was an old crab. It says the Classical master taught Laughing and Grief and the lessons would decrease in time everyday. The Classical master teaches them emotions, but we learn them naturally. This may be their natural teacher that teaches them these emotions, but instead we teach ourselves when we we're children. The reason why the lessons would lessen each day because like an old man or old woman, they seem to experience everything in this life. So whenever someone grows up they learn all these emotions and other experiences from life and eventually experience everything and learn everything. So for them the lessons lessen each day.
