1) person makes mistake. they knew it was wrong, but did it anyway due to emotional weakness. then they try to get their friends/girlfriend/boyfriend to forgive them, but those people are mean to them about it for a while. then they all forgive each other.
2) person has a problem. this makes him feel bad and avoid his friends and family. then after some time he finally asks them for help. they say they are "there for him" and they hug and then the problem is suddenly trivial to solve.
There are no genuine disagreements or ignorance. Everyone always knows what's right and it's just a matter of doing it. And there are no genuine problems that require problem solving skill and creativity. People know how to solve all problems, it's just a matter of having friends and family help out.
In other words, life doesn't require knowledge or thinking. Life just requires keeping control over your emotions and trusting your friends.
One Tree Hill's motto could be: the cause of, and solution to, all of life's problems, is not beer, but feelings.
