To say or not to say, one better weighs upon it!
Keep this handy rule with you always: no need to let those words out of your mouth which can hurt a person more than anything else.
I follow this rule quite often and the wonders it can do. Yes, you may find yourself in a situation where one has to say something but even in those moments, keep yourself in control.
Words are very powerful. One wrong slip and they can destory lives and worlds.
