Life is an unknown journey. Everything, every moment is unknown. Although we can predict the outcome on a few occasions, most of the times future remains unpredictable. In this journey we make friends and relatives. Whose behavior towards us is pretty much predictable, e.g. I know how my mom will care for me when I go to my native place after many months. This also is a function of time and space. A mom in USA will not have the same feelings (or expression of feelings) for and the same expectations from her son as a mom in India. The relations mean differently in different parts of the globe.
NBC news channel here once reported that people have 40-45 % divorce rate in USA. Even the couples over 60 have around 40 % chances of getting divorced. I am sure these couples would have spent over 10 times more money on their honeymoon than an average Indian couple. (I am yet to go on a honeymoon after 7 months of my marriage.)
So, it implies that these cosmetic affections do not promise a stronger bonding. An Indian husband can not tell his wife, “Well, it was nice living with you these 5 years, may be we should look for a change.”
