My husband had just bought a new washing machine for me . I decided to use it the very day and I washed a lot of things . Everything worked well , but I found one of my husband's socks   missing . I looked everywhere for it , but I couldn't find it anywhere . The next morning , I got ready for school as usual . When the bell rang , the students came in . I greeted them and told them what we were going to do that day . When I turned around to write on the blackboard , the class bursted out a roar  ! They laughed and laughed . They laughed so much , in fact ,that I was afraid the headmaster would be in to see all this . I asked the class to stop , but the more I talked , the more they laughed . I decided to pay no attention to them and I continued to write on the blackboard . when I did this , they roared even more . Finally , the teacher who had the room next to mine came in to see what all the laughter was about . "Good heavens ," I said , "Will someone please tell me what is so funny?" "Oh , God," said the teacher , "You have a brown sock to the back of your skirt !" So that's how I found my husband's missing sock . "Oh , well ," I said to the class , "Let's just say you have had an unforgettable lesson on static electricity . " What was the writer ?
