I had a friend who died young, I was young as well. I went to his funeral and there was an opportunity to speak about him and our memories of him. No one stood up to speak. It was awful. I wanted to stand up and say he was a good friend, and to say I would miss him, but I didn't. I've regretted that ever since - 30 years now, and I think about it frequently.
But it's a somewhat odd custom no? Funerals. Probably no one stood up to talk because it felt awkward, as it is. It's not like you hurt your friends feelings for not speaking up.
She teaches that when it comes to death and dying and supporting other going through the process, be present, neutral, kind, and courageous. It is hard and awkward to get up to speak. And no shame in not doing it, especially as a more distant connection. But also a lot of good can come from it as well.
