I think that is very important to divide duties. When only one person cleans all house is more tired and it takes more time. It?s cause conflicts in family. So it is more fear. For example: Woman cooks and washes. Man does the vacuuming and cleans a car, sometimes he also repairs broken things at home. Children clean their rooms, water plants and take the rubbish out. Everyone does what they can. Duties are divided according to age and physical strength. If it is like this everything is faster and there aren?t conflicts in family. But thanks to divided duties, we learn how to work in a group. Everybody does something. In my family are duties divide and I?m happy about this.
