That's why no one will look into the eyes of a disfellowshipped person.
While I was never brave enough to openly talk with a DF person at the KH, I most certainly looked them in the eyes and smiled. Again, that does not absolve me from my terrible sin of shunning persons based on what a group of three middle aged clueless men in polyester told me to do from a platform. It was wrong then; I knew it then; I still did it, but as usual, found "innocuous" ways in which to manifest my disapproval for the entire process of shunning.
I remember one sister's daughter was DF for getting pregnant (the boy involved was not - the reason being that she was "notorious" because she was pregnant....the WTS will always and forever find a way to punish women for their ability to create a life), and the sister with whom I studied said, "I'd like to call T. but I can't. Suppose her daughter answers the phone? I certainly don't want to say a greeting to her."
So, "T" never got phone calls from "C" merely because "C" did not want to speak with the DF daughter. How Christian was that?
Incidentally, "T" told me in advance her daughter was being DF. She mentioned this in front of about three other sisters besides myself. She said, "I just don't have the heart to sit there and go through that announcement and the humiliation." The other sisters were shocked when I said, "Well then, don't go." The counter-arguments were that this was a loving arrangement of Jehovah with which she needed to show she was in full agreement. (By the way, she wasn't.)
"T" took my advice. She stayed home.
