Knives. Guns. Baseball bats. Clubs. Nunchaku. Swords. All are weapons and all, when used in the right manner, can be deadly, or, at the very minimum, extremely harmful.
But when I think about it, the most powerful weapon of all isn't an actual weapon and it can't physically kill or harm anyone. On the surface, it doesn't seem that powerful, but that's a deceptive facade, as it's actually incredibly powerful and damaging.
What is this weapon? Words.
Be careful with your words, for sometimes, even when they're said in an off-hand or joking manner, they may wound more deeply than you realize. And, much like the gun that's been fired or the club that's been swung, they can't be taken back. Yes, you can explain or even apologize, but the hurt's still there. And you know what? It doesn't always go away easily.
