"Duster"

I was in first grade. I have always been a person with low self esteem and extremely scared of anyone and anything. Sunita teacher was my class teacher (Every class is assigned a class teacher, who takes attendance, calls your parents if you have been bad etc). I was really scared of her. Well I was scared of any and every teacher, since some of them used to beat you up, in case you did something wrong. One day, she asked me "You! The smallest one in the third bench, go and clean the duster." Scared and having no idea how to clean a duster I went outside the class. I thought to myself, "Hmmm now how do people clean a duster?; Do you wash them?, Ugh!". I went to the toilet, i put a little water, "No!! This is just making it worse." Confused and scared to go to class without completing what my teacher told me to do, I stand outside my class. After ten minutes of wandering, I met a boy who was may be 2-3 years elder to me. He comes up to me and asks, "Were you punished?", "Why did you do?" I explained that I was not punished, but I was in a difficult situation. He could not stop laughing. He came up to me, and told "You just hit the duster as hard as u can to the wall or pillar till you feel like its clean." He cleans it for me, I go into class, lie to the teacher that I was lost, which made the class laugh and I sat there with the satisfaction that I accomplished the task (Or in reality, got it accomplished ;) )
