No, it’s not, and you have no reason to feel bad. Let them talk, they will finally get bored. I was only on a funeral once, it was a funeral of a dear family member. My brother didn’t cry, but it wasn’t because he didn’t care, the family member was sick for a very long time and he was just emotionally ready. Our far family members talked about him too, but it didn’t bother him. That kind of rude family members don’t deserve attention.
Sorry, I created kind of a rant here
