" One way to test whether you have chosen your friends wisely is to ask yourself why they are your friends. If your only answer is that you like them and they are fun to be with (certainly important components of friendship), you probably haven’t given consideration to their values. Or try this: what case could you make to people who have never met your friends to prove that your friends are good people? "
