Family is very important to every person. Belonging to a family is one bond almost everyone in the world shares. One sign that this is true is that people usually show great concern about the family as an institution.
There are many different types of families. While most families are traditional, comprising a father, a mother and one or more children some of them are headed by one parent, usually a woman. In a few families there are no children. These childless couples may believe that they would not make good parents, they may want freedom from the responsibilities of children; or perhaps, they are not physically able to have children. Other families have one adult who is a stepparent. A stepmother or stepfather is a person who joins a family by marrying a father or mother.
