It's hard, I can relate to your feelings.
I usually head for the door straight after the closing prayer. Like DD said, the majority of JWs are good people who are just captives of a concept. I don't have any problem with the bros or sisters, but find it hard to pretend that I like being there.
I try to arrive just on time and leave straight away. My wife is awake and we are in aggressive fade mode, because we can't do this forever. The family will just have to accept our position whenever it is that we finally stop attending, that is if I don't get DF'd before then.
