Mumut was annoyed when three days later returned to meet Dora, her friend from junior high school. Dora shamelessly described her as a poor person, even telling mothers who were waiting for their children that she was a maid who seduced her employer. Mumut is furious with Dora. In fact, she and Dora used to be quite close because Mumut often helped Dora with her duties in return for Dora to treat her to the cafeteria. For poor Mumut, it is a symbiosis of mutualism. After all, she can eat lunch for free because she never has money to buy lunch.
