My viewpoint is that I could never do it. But I get that some can do it.
Keep in mind that the moment they reinstate you, you don't have to be there anymore. You don't need to accept their calls anymore, don't need to work on getting "privileges" back, don't have to be turning in time slips- none of it.
If you manage to kiss ass long enough to get reinstated, don't keep wasting your life at a Kingdom Hall.
