I complained to my father, my life is miserable, I do not know how to continue living. The cook's father brought me to the kitchen. He added water to each of the three pots and set it on high heat. When the water in the three-pot boiling, he put the potato in the first pot, put the eggs in the second pot, and finally put the ground coffee beans into the third pot.
Then he put them in boiling water and cooked them without saying anything to me. Twenty minutes later, he switched off the cooker, took potatoes and eggs out of the pot, and put them in two separate bowls. Then he filled the coffee with a spoon and put it in a cup. He asked me, "Child, what do you see?"
‘Potatoes, eggs and coffee!’ I answered. ‘Look carefully,’ he said, ‘touch the potatoes.’ I noticed the potatoes were soft and observed that the cooked eggs hardened. Finally, my father asked me to take a coffee. "Dad, what does it mean?" I asked.
Then his father explained that the three experienced the same adversity - boiling water. The reaction is different. Potatoes began to be hard and indomitable, but in boiling water they became weak. Egg fragile, only the outer shell that protect the inside of the egg. But when you put it in boiling water, the eggs harden. Grind coffee beans are unique, into the boiling water, change the water, creating new things. ‘Which one are you?’ He asked me. ‘How do you deal with it when it is unfortunate? Are you a potato, an egg or a coffee bean?’
one-way degassing valve to explain the moral: life, the outcome of the matter depends on our good or bad.
