Funerals/ Memorial Services can vary enormously among the JW movement. Of course they all contain an element of “witnessing for the Kingdom “ but the better ones slip it in gently . I have been to some cringe-worthy services and some that were done respectfully.
I tackled the speaker after a relatives funeral for trying to be funny in it.. Jokes are not appreciated when you are grieving. Others have been better. The last one agreed to play conventional music rather than WT stuff, at the bereaved’s request.
