Cleaning Day

When I am going to watch TV on Sunday morning, my mother suddenly asks me to do the cleaning. I never do it before. I don't know why my mother asks me to do it suddenly. I clean the floor and then I go to the sofa for a rest, and I think I have finished. But my mother comes to me and asks me to clean the toilet. I feel sad. Toilet is so dirty. I don't want to do it, but I have to. After doing it, I realize what a hard job my mother is doing in the usual time.
