As usual, minimus, has some good ideas about the school. As a sister, I have less value, so my quitting the school was not as big a deal. I did use the same technique, illness and work, and after a pattern of that, telling the school overseer that I wanted to be taken out of the school "temporarily" until I could be sure of fulfilling my assignments and not putting an extra burden on him or any substitute students. It worked like a charm and I have been out for 2 years.
Eventually, though, final decisions will have to be made. Think of all the JWs you socialize with only at the KH? Then think of the ones that call you or see you apart from the KH? Unless you are a popular guy, the second group is dramatically smaller. Most JWs use the meetings at the KH as a social setting. So when you go to your last meeting, it will seem strange because you will probably have little or no contact with the first group.
I always think real friends are like Jonathan whose father was trying to kill Jonathan's best friend David. Jonathan defied his father several times to support his friend. It didn't matter to Jonathan that he had lost the kingship to David. It didn't matter to Jonathan that his own father almost killed him, his own son. Jonathan knew his father was wrong and the God did not support him.
So Matty and minimus, and the others like us, if we want to do the slow fade, we have to be patient but forward moving, and honest with ourselves that this will not be without pain or casualties of some kind.
