"When you were a kid and wanted to do something your parents or teachers didn't like, you may have heard the question, "If everyone else jumped off a bridge, would you?" The idea is that it's not good to do something stupid, even if everyone else is doing it. The logic is think for yourself instead of following the crowd. ...But one day, you grow up and suddenly the tables are turned. People start expecting you to behave very much like they do. If you disagree and don't conform to their expectations, some of them get confused or irritated. It's almost as if they are asking: "Hey, everyone else is jumping off the bridge. Why aren't you?""
