Poonam, firstly, you don't take another culture - you adopt it. Secondly you don't HAVE to. You have choices. It always surprises me that in India we seem to be very underconfident about our culture and fear the fact that another culture could replace the existing one. Thirdly, speaking another language does not dilute your culture, it merely enhances you as a person. think about it and stop being so fearful.
