Indian culture is different from Western culture. Most of them (Not all) are not used to mingle with girls, so they don't know how to talk to them. Those who know, are not shy at all. They keep asking why you leave alone because in India, majority of people live with parents until they are married (some even after). But this should not be seen as the general rule, only majority of them. But some Indians are nice, good-natured, talkative and very out going :) Don't categorize them please, they are nice people :)

Because India id country with strong traditions, but now globalisation is chanching everything everywhere
