One player is chosen to be "IT" They are blindfolded and sit on a chair in the middle of the room. The other players run round the chair until the leader gives a signal to stop. The player immediately infront of the chair says "Hi there, I'm Susie" in their normal voice. The blindfolded player answers, "No you're not, you're ?", guessing at the real identity. If they guess correctly the two players change places. If not the blindfolded player remains blindfolded, and the players run around again
