Sweet or Sour

This is a game you can play by yourself, or with a bunch of friends. Played while walking on the side of a busy street or in the back of a bus or car. Wave to all of the cars that pass or are behind you (Car or bus). When a person in the car waves back, you call them 'sweet,' and you get a point. If nobody in the car waves to you, or makes an obscene or mean gesture, you call them 'sour,' and no points are added. Although this is mostly a game of luck, some strategy is involved. Try making your 'sweetest' face so you get the most points.
