Agree. My wife passed last December and as per our plan, she was cremated. I gave instructions to my children that when I die, I'm cremated and our ashes will occupy the same urn so we'll always be together and they're welcome to join us. Very old school in some cultures.
Good for you, Sam. I can't speak for your children, but as an outsider, I recognize how much you must love them to make these decisions yourself.
