Yes, I know what you mean. I dread JW funerals too, but go out of respect for the person who has passed away, especially if they were a close family member. Unfortunately it involves gritting your teeth and sitting through the lecture from the platform. It seems the primary theme of any JW funeral is to ensure the captive audience have an earful of WT doctrines and to try and shame the ex JWs into returning to the clutches of the Borg.
The life and times of the deceased comes waaaay down the list of priorities and must be fitted into a set outline issued by the Society. At the last funeral we attended, nothing was said about our deceased relative's life other than how much of her time she gave to knocking doors, attending meetings and assemblies, bringing bible studies into the 'Truth' etc. Her personal life experiences and achievements were barely touched upon!! Nobody would have known what she was like as an individual.
Just try and switch your mind off from the drivel coming from the platform and think about your loved ones, which is the reason you are there. Your support will be very much appreciated by the people who matter, I am sure.
