Different cultures bring with them their own richness and learning. Not only will you be getting married and that means a new situation for you but you might also be entering into a new family situation with new traditions, ways of living and expectations that need to be realised.
You may think you have an understanding of your fiancée's culture as you have been together for a while but most of your time will probably have been spent as a couple and not with their family and that is a different matter altogether. You may well have spent time popping in and out of their home but not necessarily had any deep meaningful discussions with them about their expectations, hopes and fears.
