If the name of the friend class is same as that of the enclosing class which is nested then the nested class is a friend of enclosing class.

Thrice blessed are the son and the mother between whom there exists an association not only physical and affectional, but spiritual and intellectual, and broad and wise as is the scope of each being.”
