Caution

I am sitting in the Minneapolis/Saint Paul Airport waiting for our flight to Bismarck, ND. Periodically, I hear a suave female voice with a British accent announcing, "Caution, you are reaching the end of the moving walkway." emanating from the delightful moving walkways positioned behind our gate. This made me wish for my own warning system announced by a suave British woman. "Caution, you are reaching the end of your mother's patience." That way, when I am starting to get really upset, I wouldn't have to express this to my boys, they would be warned in a calm, reasonable way. Maybe this could work for husbands too. "Caution, you are reaching the end of your wife's rope. Please stop what you are doing and plan a romantic evening out." If men listen to the voice on their GPS, surely they would listen to this advice as well. Do you think there are already patents out on personal warning systems?
