There is no road walked...

...that doesn't leave it's mark on us, body and soul.  It is easy to fall into if, and if only. If only I had, or if only they hadn't I'd be so much happier now. Beware such thoughts indulged for more than a passing glance, for they can only invite bitterness and regret into a life.  No one can reconstruct their life as a simulation to know such things with certainty.  Such simulations are beyond the scope of mortals, and where God could most likely take a real good guess even he would still be guessing to a degree so long as his children have the free will to choose the roads they'll travel.  If and if only are dangerous, they have a backbite and leave an aftertaste.
