I advance NO theory. I never have.
You are the one who has admitted to being afraid of asking for an official to explain to you about whether or not a BC MUST be issued BEFORE a DC can be issued. You keep running all over the place making up nonsense to avoid getting an OFFICIAL answer to your concern.
You are still putzing around in a little circle all by yourself.
If you stop replying to me and send an email to a US funeral home, you will set yourself aright.
Let me know what they say to you.
