Sour Milk and Crunchy Cereal

In this chapter, they discuss their experience with a new supermarket and the milk they bought from there. They taste the cereal with the milk and find the pieces to be very crunchy. However, one of them realizes there might be something wrong with their milk as it tastes sour. They debate whether the milk is actually bad or if it's the cereal they had earlier. The chapter ends with one of them wanting to brush their teeth to get rid of the taste.
