Do you remember playing the trust game, where one person falls backwards and (hopefully) someone catches them? I’m sure you’ve seen it on a TV show.
Usually, on TV, it’s a sitcom and the person falls to the floor. Ouch! When you play that game, you have to trust and believe that someone will catch you. People who don’t trust and believe that someone will catch them won’t play the game, because to properly play, you have to just relax and fall.
