You should have said something like “You may not address my wife without my permission and… to answer your question I forbid my wife to vote.” (Pause so they can pick their jaws up off the floor) Then say “Just kidding, that’s Islam and sharia law. This is America and she can do whatever she wants and doesn’t need my permission”. For added effect you should roll on the floor laughing hysterically working in between laughter and gasping for air something about them being stupid fucks that actually believe that shit.
I see how frustrated you get with your kids. I have young adult children also. I feel your pain. Might as well have some fun with it.
