I never shunned, but I never went out of my way to keep in contact with DF'ed one's (very often anyway). I still feel like shit about that sometimes.
GetBusyLiving, I know just how you feel. Oh how I wish I had kept in touch with some of my friends over the years that were DF'd. But no, I was a good little witness who never looked back for those who "fell away." Sheesh. Now I'd love to find them.
Of course, this is a very selfish point. I do feel terrible about how my shunning ways no doubt affected others. Yuck, I'm a jerk. For the most part, I just avoided those who were df'd. Although I never had the experience of having a very close friend/family member df'd. I come from a huge family of witnesses. Four (five?) generations worth. They bleed watchtower red. Haven't spoken to any family in two years.
