Reminds one of the plight of parents living in Chettinaad and Nellai districts, whose children had migrated to Bombay or Madras. A group of relatives will surround the postman (or school vadhiyar as the case may be), who reads out from an inland letter, minor little details involving trips to Gateway of India. This system was more efficient because the postman read out all such letters to a common audience and so the second-level relay of communications was rendered unnecessary.
For the NRI, the passing away of the audience to their movie, is sorely missed, if it occurs well before the "transition time". Then the NRI is rudely awoken from a dream sequence. Transition time is when children get bored of playing out this elaborate movie for their parents and instead turn around to start watching the movie of their kid's life.
This is where a joint family system is valuable. The pain of having to communicate every minor little detail to parents is unnecessary. There is no need for the NRI to pretend to folks back home that he is a "modern man" who (a) helps around the house and (b) is demonstrative about his love for children and wife. One can move on unmindful of these silly botherations and can cease to be this 'live show' for people in far away lands.
One can just live life.
