Vonnegut, in the next chapter, makes fun of life for a person as they are aging. They have kids who are all grown up, who never come to visit. They lose old friends that they can not come in contact with. The only companion to them becomes their dog. They drink away their lives and listen to news shows or late night television.

All in all, Vonnegut seems to be just saying: after a certain point in your life, you simply waste away. Days become mundane, more mundane than schools days for students [and teachers].
