8. The relationship of a Husband & Wife is a very Special one . I believe that the following reasons make this relationship, so special .
              (1). As humans we all want that someone should be there just for us, like we want to                     be for that someone ; someone we can call our own & who is dedicated to us
                    alone, just like we want to be dedicated to that someone . Someone, whom, we do
                    not share with others. Ya...we've parents for us, but they are not exclusively for
                    us. They are dedicated to each other & also they are equally there for our                                  brothers/sisters. And, moreover, there's always a gap between us & our parents ;
                    we can't talk about 'everything under the sun' with them . There are certain
                    restrictions, a certain kind of  invisible wall between us & our parents.
              (2). As is the process of evolution, life-partners are the only one for whom we can say,                     with maximum surity, that they will be with us everytime/everywhere & in every                     circumstance. Kids will grow up & leave you one day to build their own world                     with their life-partner. Parents may not come to every place with you cause as
                    they grow old they would tend to prefer a more stable/static life & so may prefer
                    to settle in one particular place. But your life-partner will always be there for
                    you, with you, in any circumstance with an understanding that can not be
                    matched by any other individual. This is the reason why 'Husband-Wife' are
                    considered as one soul.
              (3). The Understanding, Trust, Love, Devotion & Respect that is shared between                      life-partners can not be matched for the same by any other individual.

          9. According to my observation, I've found that the First Priority of a Husband is his wife & that of a Wife is her kids. I feel this sequence of priorities is justified ; since the role of a male is generally considered to be that of a 'Protector of the family' & that of the female is generally the 'Nurturer of the family'.
                                 Since, wife is the top priority of a male, he'll do his Best for her Happiness & Protection. And since, children are the top priority of a female, she'll do her Best for their Happiness & Protection. So, directly or indirectly, everyone will ensure the happiness & protection of every other member of his/her family.
