Bill Cosby was right

I think Bill Cosby is brilliant. 
He once stated that parents don't care about "fair" when their children quarrel.  All a parent cares about is "quiet". 
This is true.  I don't care who called who a 'stupid-head' I want you both to shut up.  If two children are yelling and fighting at each other, I will put them both on a time-out since I don't care who started it, I just want it stopped.   (Much like police work, I might add.  Except at home you can't get out of timeout by posting bail.)
I was home this evening and could overhear my two youngest children interacting in a bedroom.  Seth is 7 years old.  Grace is 4 years old.   I wish I could sum up the personalities of these two in a few short sentences, but the truth is, I can't.  They are adorably frustrating, perfectly misbehaved, have great bad manners, and sweet potty mouths.  One likes weapons and the other likes dangerous animals. 
Anyway, I could hear them in one of the bedrooms down the hall and they were playing with each other and laughing.  But, inevitably, one of them started crying.  I mentioned previously that I have an injured foot and though it is getting better, it still bothers me.  So I was not quick off the couch to go see what the matter was and settle it with perfect equality.  (Namely, sending them both to a time-out.)  So before I intervened, I noticed that after a minute or two of name-calling and crying, they both started playing again and laughing. 
Another remark Bill Cosby made was that kids change moods so quickly.  As I sat and listened I realized that a pattern was repeating itself.  They would play for a while and then call each other names and cry and then go back to playing.  So the question in my mind is, "Am I too quick to intervene when the kids start bickering?" 
I think current pop-psychology and our media-dominated culture suggests that we try to ensure that our children are kept from discomfort and confrontation as much as possible.  Confrontation is a huge part of our lives.  We can't reach our goals if we are not willing to confront the obstacles in our way.  Perhaps it is better to allow them to deal with those circumstances in a safe place, like home.  They will never go through life without people calling them names or events not going the way they want them to.  They will most certainly come into contact with a bully at least once.  Are we ruining our children by trying to protect them too much from the ups-and-downs of life? 
I think so.  If you don't like it and start making a fuss, I'll put you on time-out.  I said I want QUIET.
