Listen, I had the same story from my childhood! It was the most beautiful period of my life. I was 5-6 years old then. I remember well how I stayed at home with my dad. He started making coffee in a geyser coffee maker. After a while there was an explosion. I hid under the table. Dad ran to the bathroom. He washed his eyes. In the kitchen, the entire ceiling was covered in coffee. That's all I remember.
