Grandma’s Footsteps in Britain, Red light, green light in North America, Thunder, weather, lightning in Austria, One, two, three, ciggy forty-three in Argentina, Frozen in Mexico, Statues in Greece – all refer to a game of stealth and balance popular around the world. While some versions rely on turning around at unpredictable intervals, these London kids play it with the regularly timed cry of “One, two, three, freeze!”. The caller takes her time assessing everyone’s immobility, which ensures further wobbles. But she can only expel the most unstable, and the forwards progress won’t be stopped.
