Your mother is the first to talk.

Your mother stands up straight and talks to you aggressively, once she is sure her future husband is out of earshot, "I am confident that there is absolutely nothing in the matter of state secrets we need to discuss at this very moment. So, what is your real reason for wanting the love of my life out of the room?"

You grin back at your confident mother. "I wouldn't be so confident that state secrets will not be discussed or occurred here. In fact, from this moment on, anything said, or that occurs here will be a state secret. And the punishment for telling anyone else, including your future husband, what occurred here will be death for not only the teller but also anyone that hears it. Do you understand?"
