Having met my fiance, I love the way he can talk to the elders with the correct respect as well as my brother, my cousins etc and get along with everyone.
It also happens the two families actually knew each other back in the days. So everyone loved it that the two of us are getting married.
With Indian weddings, it's not just the couple that are getting married, it is the families getting married too. The more compatible they are, the easier this transaction is and the happier everyone is.
My parents are quite "old-skool". In fact Indians in India are more modern than my family. This is because I'm third generation born out of India and you normally see people trying to hold onto their customs and culture more, the further away they are from their origins.
