no, i think its an idiotic, arrogant and somewhat childish way to live.
if you owe someone an apology or you yourself feel sorry for your actions then you should do the right thing and apologise.
if you are misunderstood, or you have done something wrong, but for good reason perhaps etc then you should explain.
most people like this have a very different opinion when its them that require the apology or explanation....
you wouldnt get far in court if you stuck to that haha
