What do families most often regret about the funeral they arranged?

I think what most people regret is not being true to themselves and their loved ones. So if there's a particular song you want played but you think you know, it might not be perceived in the best light by funeral attendees, then I would suggest just not worrying about that and going ahead with what you'd like to do, or what your loved one might have liked. Because oftentimes that's the things that you're going to remember about the service, and that's going to help with closure. And you're not going to be thinking about what someone thought about your funeral arrangements in the days coming, in the days and weeks following the funeral.
