While you are supervising playground activity during recess, the children are playing a game of tag. As Marlene and Shelly run past each other in opposite directions, Marlene reaches out and touches the shiny logo on Shelly’s jacket. Shelly starts to cry and says that Marlene poked her really hard. Marlene says she didn’t poke her, she only touched Shelly’s jacket. Each child thinks the other is lying. Can you explain why both children are correct?
