ABCD and ABCC are true?

Lot of times,i have thought about this!! some of my cousins are natives of america ( born and brought up there), whenever they come to india, my mother face a huge pressure of handling them which i have noticed and in turn she vents her frustration at us. usually this does not happen to my other cousins who are breathing indian air. Then i seriously think is it due to the huge cultural difference which they have adapted r adopted?? The curious thing about them is they still want to show their nativeness in the way they behave but don't know where to draw a line. simple example is of my cousin who told me, she never wears sari to her work because of people looking at her as alien, but when she is in india,buys a lot of saris.

I was surprised where will she wear that and asked her a question "where will u wear this"?? she replied, in functions, i screwed her by saying what are all the functions she attend,she was kinda pissed off and could not handle my bundles of questions. Then i realised that this people try to be the native at home ( indian or chinese at home), at work try to be american,that is why they are aptly called, for indians, ABCD (American born confused desi) and chinese as ABCC(American born confused chinese) who loath their native for the false system and contribute nothing to the home land. They try to inherit the american culture in them but mix too much of their native values which obviously gives rise to lot of complications. For example, if a girl child is born in america and bought up there, obviously the child will get accustomed to amercian system but the parents try to instill indianness saying "you should not wear this and that, which is obscene". Anyway that is not going to be practically possible at those countries where the child is going to be very independent after early ages.
