..to me one most important donts is to shut up.. when you are angry...or walk away from the scene..
..how many heart has been hurt..
..how many friendships has been broken and unmend ever..
..how many regrets we must go through again and again...
So, Listen !...DO NOT SPEAK WHEN YOU ARE ANGRY...
and you can definitely, i guarantee save a lot..
..you save the regrets, heartbroken, friendships and most of all a peaceful night sleep. PERIOD.
