sure it's not simple, but if people tried to tolerate each other think of all the fights we can avoid.
I.E.: a group of people are acting immature, but they are just having fun. however, one person decides to tell them to shut up (instead of asking nicely) and one of the immature people flips them off. a fight breaks out.
let's look at this situation in a different view: people act immature all the time, no big deal, but it CAN get annoying. the person should have asked them nicely. even if the immature person still flipped them off, tolerance is learning to ignore that and just walk away.
who is the bigger person?
