Sometimes, when someone shared something they feel great about with you, would you laugh? And why do you laugh? Is it because you are happy that your friend is happy? Or just an act so that your relationship with the person is sustained? And so what if people do not rejoice as you did when you shared something joyful to you with the person? How would you feel? Should you feel "rock-bottom" that the friend do not share the same sentiment? Wouldnt that make friendship nothing but mere selfish pursuit of self? That you would expect them to feel the way you do? If not, you wouldnt feel happy? Or you wouldnt feel great? Then what makes a friend, "friend"? and not acquaintance? Nor simply a tool of help? Or a commodity of trade? Passer-by? There are just so many "actings" and "compromising" to do in any relationships, I wonder what would life be like as a hermit? Perhaps thats why the Task-Specificity model explains Social Relationships better, as we approach different people for different intention. Are there then what Bo Ya considered as "True Friend"? "The One Who Knows My Music"? "Soul Mate"?
