There are lots and lots of developments which we see daily happening, atleast at the metro cities of India. But Indians usually keep their traditions alive wherever they go, be it town or city.
They keep in touch with their predecessors by say,
1 . Phone
2. Following the customs
3. Making associations
Even though they get new invites from other customs, they still cherish their own. Thus custom binds previous generation to current. Hence, all feel belonged to one or the other community via customs.
If someone wants to run away, which we see in the current generation, they long for identity after a while. Hence comes the origin of insane identity.
