One day, I was cooking in the kitchen as the telephone rang. I went to answer 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 beef was badly burnt. I quickly turned off the
gas, opening all the windows, and then went out of the house. With my surprise, two fire engines
were outside of my house. I was rather worried. I told about the firemen that it was my careless
cooking which caused the heavy smoke.
