"Bad luck always comes in three" and last Saturday seemed to prove it． After trouble with the car, the television, we spent the evening waiting for the next trouble． Shortly after dinner we both smelled smoke． My wife, who was often careless when cooking, ran to the kitchen but returned looking puzzled． I rushed up the stairs to see smoke coming from under our bedroom door． I went to the bathroom and tied a wet cloth over my face． Then I returned to the bedroom, opened the door and crawled(爬) in—there would be less smoke at floor level． With one hand reaching out in front of me I advanced carefully feeling for the switch to turn off the electric blanket． At that moment I heard the bell of a coming fire engine． Thank goodness my wife had not been wasting her time．
