OMG. I think this is terrible behavior! In general, from the very childhood, I was taught that you cannot joke and behave inappropriately at such ceremonies as funerals. Unfortunately, children and as we can see from this news, even some adults don't know about that. By the way, not long ago, the whole of our family was choosing a headstone memorial for our grandmother (you can find more here) and suddenly my sister's daughter, who is about 7 years old, started laughing and saying that it would be better to cremate grandmother! When I heard that, I had nothing to say...
