Well I think the average JW would probably hide the shunning from their family, and may even fake a smile or speak with the disfellowshipped family member, just to give the impression that they arent a family destroying religion, because they know it would stumble their "worldly" family members to find out the real truth. I have explained the shunning doctrine to several of my distant relatives, they were really surprised to find out it truly existed.
