What do you mean by “public funeral”? What’s the alternative? It sounds like you’d consider an event with only friends and family where there was a coffin in a room to be a “public funeral”. That seems to be what most people have, but it isn’t very public. Is a non-public funeral one where the family makes the coffin themselves and there’s no event where people see the dead person and the coffin?
