Krótka historia z przeszłości

When i was 10 years old my friend Michał came to my house and we were playing a computer games. We were alone in home because my parents go to do some shopping. Michał had an idea to make some chips. I liked this idea because i was really hungry. I spill some oil on skillet and put it on the cooker. When oil was warming up we came back to the computer and forgot about it. When i smell some smoke i realise that we forgot about oil. I go to the kitchen and i saw that everything is in fire. I call for fire service. When my parents came back to home their were very angry. Because of that i was grounded for two weeks.
