In 1996 we were in a Greyhound bus heading across Texas. In the South-West the messages, given by the driver, were in Spanish as well as English -- usually. Our driver was an exception. As the sky went black and the wind sprang up he gave us this warning: "We've got a tornado warning. When I tell you -- get under the seats and stay away from the windows. If you didn't understand that -- ask another passenger to translate it for you." Que?
