I've known a number of new Catholics to complain that their new Catholic parishes aren't as loving and friendly as their old Prot church. That's true. Catholics don't follow the love bomb the new people methold and so what? You go to church to meet Jesus, not to party down.
Rocky and I have been at the same suburban parish for going on two years and people (I't just the working class folks. The upper class ones still don't speak, interestingly enough.) are only now just starting to warm up to us. I'm a lone wolf anyway so this never bothered me. I'm just happy that they've stopped looking surprised when we walk in.
One of my relatives is a Jehovah's Witness. He has no friends outside the Kingdom Hal and that's the way the JWs want it. Since his whole social life revolves around the hall he'll be less likely to ever leave because naturally he don't want to lose everything. It's a mind control method.
