Put your hand up if you cannot read the following word: STOP. And now put your other hand up if you struggle to identify colors (those who are color blind are exempt) and never got nature's message that red is the color of danger. There's a lot of people with 2 hands up right now. And I'm not going to ask if these people know what an octagon is. That's just asking for trouble.
People waving their hands in the air and shouting "me, me, me!": 1 star.
