unplanned peace

ok, I'm going to pick up the kidlettes(to them they are teenagers!), I am expecting a word war with my youngest.  He shocks me out of the water by being agreeable and pleasant.  What planet am I on?  The previous pick-up, he was a raving insult-spewing 12 year old temper tantrum.  Well, my peace for today has come in the form of a battle the I was ready to take on but didn't have to.  So much for being prepared!  But, I,ll take the change in circumstances gracefully and full of gratitude.  Thank you Divine Powers.
