So I have a JW relative now living with me so I went to the Memorial this year with him since he is new to the hall and doesn't really know anyone. The warmth was amazing (insert sarcasm here). One witness couple that has been stopping by and relatively new to the area saved us seats so they talked to me, one other sister and her brother talked to me. One elder stood at the back door and all he said to me was, "I know you". That was it.
My relative, an active witness, has been going to this hall for about 2 months now. Other than the one family mentioned above, I don't think anyone has bothered to get to know him. It really is an unfriendly congregation.
