OhIamfree, my experience was pretty much the same. here were maybe three or four people that I knew well enough to talk to, everyone else pretty much acted like I was invisible. Sometimes people would ask me if I was new or a visitor.
The bible says that the identifying mark of true Christians is that they show love to one another. Not the preaching work, but love. The Watchtower almost never talks about helping others in the congregation, the only thing that counts is going out knocking on doors.
Any church that treated each other that way would be empty, people would leave find a church that made them feel welcome. Jehovah's Witnesses have no choice, as most congregations are exactly the same, more gossip than interest, more judgement than love. People stay because they have been brainwashed to accept this treatment, but it isn't normal and it isn't right.
