Walk a Mile in Each Other’s Shoes

Play a game in which, for a set period of time, each sibling must pretend to be the other. You might even have them trade shirts or shoes to facilitate the role play. The main rule is that making fun of the other person is strictly forbidden. The point of the game is to really try to imagine what it is like to be the other person. Give lots of direction so that each sibling gets to really feel how their annoying behaviors impact the other person.
