Everywhere it's the same

There are different kinds of love we experience in our life. Love of mother, father, brother, sister, friends, relatives, boyfriend, girlfriend, wife, son, daughter. Though it emanates from different sources, it serves a single purpose, that is, wherever it may be coming from, all we feel is that special warm feeling with un-timed affection and selfishness that you belong to them. It was shown to us in different forms by different people at different situations. When your mom backs you up for your mischief, when your father gives you money though he knew you would squander, when your sibling supports your foolish decisions, when your friend scold you for your wrong, when your crying baby runs into your arms, when your spouse takes you into their arms when you are distressed or when everybody here keeps compelling or advising you every time to be the best. Everybody have their own way of expressing their love on us. It depends on how well we can understand it. We can't point out and say love is "this, this and this". Love is no different from one person to other. It is Unique, though it takes different forms to reaches you, like human race with different personalities. Love though unique, takes its form by the activities we share with other people. When someone has to feel proud about you, mom and dad bless or hug you, friends praise you, lover flaunt you, wife and children shares your pride.
We can't expect everybody to do the same thing when they are with us in a similar kind of situations. Mom makes your favorite dinner, dad gives you money, friends stick with you every time, wife sleeps with you.
So, what does it make us think that love is different with? It might be because of being old and new, or because of it's scarcity and popularity, the ease with which we can move. Not that your love on your lover is special from your love on your parents cause you can have sex with your lover. It is just what you desire from them changes. Their grief is the same when you die, they protection is the same when you are dying, their concern is the same when you are living.
Don't break the relationship with somebody for something that makes us more happy  cause the pain is similar to everybody who loves us when we leave them.
The only formal relation that we can't share with anybody in this world is our "WIFE/HUSBAND". It meant only for us. Cherish it ;-)
Still trying to understand how can a stranger comes into our life and cares us like our kin do till the end.
Maybe good relations are always gifted.
