I would like to say a few words about my dutes about the house. First of all I make my bed in the morning, then I help my mother to cook the breakfast and lay the table. After the breakfast I help her to wash all the dishes. Almost every day I vacuum the carpets in the whole house and water the flowers. If my parent's friends come to visit us, I always help my mother to clean the house after the party. I have to say that I don't like to do anything about the house, but I understand that my mother really needs some help and I try to do my best.
