Well, I don't really know when to disassociate oneself from the org, but a friend of mine(of 13 years) did it last January when she found a guy she liked at school. She had just aux. pioneered the month before, but she was sure it was the thing she wanted to do, so she sent her letter in.
Before the announcement was even made at the kh, she had moved in with the guy and his family, and her own family didn't shun her at all. Her dad(an elder on the Regional Building Committee) even bought her a car while she was gone. Some of her friends from the hall tried to talk to her at school, since they saw her every day. I never saw her(I had already graduated from high school), but I told the others to pass along a message if they managed to talk to her.
However, she's making steps to come back now. She was at the assembly last month, and brought her boyfriend too. I was an attendant, and I saw her from far off in the hallway. Even though we both knew we couldn't necessarily talk to each other(she wasn't reassociated yet), I still gave her a big smile and wave, and she smiled back. I wanted her to know that I missed her.
Okay, my boring story is over. You can wake up now.
That's what being part of Jehovah's organization is about. It's not just the WTB&TS, but the entire association of brothers and sisters worldwide. All the WTB&TS does is print literature, provide finances for traveling overseers, and provide disaster relief for those in need. You can bet they'll be in El Salvador and Guatemala soon.
