of course i would, though I would probably hate the talk. I went for my grandma and really dispised the talk. It wasn't about her at all. It was more of a Sunday public talk. He just talked about how we shouldn't be sad or cry because she was already in paradise. Then proceeded to preach to the audience. To me, it was quite rude.
But really, if your parent is a JW and requests the talk be given at the kingdom hall, I would hope everyone here would attend. Like one poster said, u may hate the talk but u will get over it. If you don't attend its something u may never get over.
these are your parents, u owe it to them no matter how u feel about their beliefs, or how they may have treated u.
