The father takes his daughter to the kitchen and boils three items - potatoes, eggs, and coffee beans - in three pots of water. He uses this demonstration to teach his daughter that when facing difficulties, people can respond differently. The potatoes became soft, the egg hardened inside its shell, and the coffee beans transformed the water into rich coffee. The father asks his daughter which one she is - implying whether she will surrender to hardships or overcome them and create positive change.
