The topic which hits me few days back, when my I had a conversation with my father after 15 min. I was amazed to feel something from that conversation, that my father talked me, like I am his friend he takes my advise by paying legitimate attention.
I always dreamt off this day when he heard me, cares me and talk to me about real world's issue. He makes me feel his issues as well. He wasn't introduced me directly, but just by expressions engulfed with his voice and at that movement I was like this is the thing. Which makes me feel I am alive.
To feel the best expressions of anger, cared, to be loved and whatever expressions you are ever thinking off. Just drilled into the heart of person by the emotion you are carrying because after rigorous practice of this you can learn the art of feeling. But the best part is you living in the land of expressions, if you are an Indian, where people used less words than expressions. Have you ever hit by the thought why relationship (of any kind, in old times lasts till the final goodbye from the world because that seeds of relationship inseminated into the land of emotion and when seeds rises it becomes farm of emotions. 
But in todays world relationship is like sweet fruit, you only enjoys the relationship till it tastes good and after that you throw its seed and waste.
But in Indian culture we had art of growing a tree of emotions which gives you that sweet fruits simultaneously and not like some two minutes noodles.
Let me fill you with an emotion, a male who grows fearless roams everywhere lives his life freely like a hippy hooligan but why suddenly he builts an empire protect it from world just to save a women, children and his parents even he knows he is the only one who enjoys the least of these. Why a women cooks everyday, clean you and your pile of dirt, keeps you healthy, burn herself bit by bit. Why an old guy in your house asking you where are you going, where were you when you are late, grilled him or herself, during his last time, when you are not doing good. Why an elder brother or sister acting like father, mother and a protector to their younger siblings and why younger one acts as a spy for you? Why they shows these emotions within family and not to everybody in the world. Because this is the concept of joint family which is still alive in India and I am proudly flaunting this character of my family.
Because of a feeling of family and these all are an expressions which they shows to each other on multiple occasions by multiple ways. And India is the only living land in this whole world where you can easily verify these all emotions.
But as time passes by we are weak in expressing ourselves without words and we need everything instantly and leave them instantly too.
That's why todays relationship can be vitnessed when one is alive otherwise it is shock to society in ancient time to see someone who broke the relation. 
I think that's why I never saw my parents to tell eachother about how much they are loving because they expressing their love with expressions of caring, fighting growing old together by seeing the generation who grows and waving at other generation for their last tour to heaven. That's why we follow rituals to show our expressions of missing them and not to show off.
