The feeling of closeness, camaraderie, friendship with like minded people you could trust.
Haven't experienced it since I left.
I see what you're saying but I think even this is conditional. If someone in the little groups doesn't like you or your family then you won't be invited to all the activities. Or sometimes they will invite people after field service, so if you didn't make it out in service you were forgotten. Another thing is most of the friendships are very superficial. Nobody wants to reveal too much because they could be seen as being "spiritually weak". What kind of friendship is that? The only real friends I have had are the ones I grew up with and even with those I wouldn't feel free to voice all my opinions about "the truth".
