One day, I was cooking in the kitchen as the telephone rings. I went to answer it immediately. She was my close friend, Lisa. When we were talking on a phone, the fire alarm sounded. I ran back to the kitchen. The room full of smoke and the beef was badly burnt. I quickly turned off the gases, opening all the window, and then went out of the house. In my surprise, two fire engines were outside my house. I was rather worried. I told about the firemen that it was my careless cooking which caused the heavy smoke.
