Mothers' love or a Girl's love ??

From birth we have been grown with love of our mother, father, brothers, sisters, cousins and friends.
Love of mother is the highest, far greatest and far weighted and nothing in world can ever try to match or compete against her love.
We never completely feel the love of mother untill and unless we miss them in some ways.

Even when she is with us pouring her love for us, why do we search someone called an unknown girl for her love? we keep on searching for that unknown girl looking everywhere.

There might be many reasons, which are they ?
Why dont we see the love near us but search another love somewhere else ?
