Do people really change?

Can a leopard changes its spots? Do people really change? Is change consistent? Or is it just a passing phase? After umpteen years, numerous reprimands, talks and discussions .... is change so temporary? Or is it one changes when it suits them and is advantageous to them? Well, we always say that water never stays calm for long. It was too good to be true. The storm will pass. Yet, it still hurts. A blunt pain yet testing the patience. At the end of the day, take a deep breath, istighfar, grind your teeth, keep your peace and silence, smile and life goes on .....   ;-}
