words hold power.

never underestimate it.
think about it. the things you say-and the things you write- can seriously change the world.
let's give an example, shall we?: how did the second world war begin? ask a historian, and he'll tell you some lame gobbledygook about the Treaty of Versailles and whatever. this is not the reason. WWII began because of words.
Germany was in a depression. they were desperate for a way to get out. and then one man stood up, and told them he had the answers. one man, a few speeches, that's all it took. a few speeches, a few words, and more than six million innocent civilians were murdered. a few years later, the world was at war.
the more you think about it, the scarier it seems. look what just a few words can do.
and this is why you should be extra careful with what you say.
saying something is like throwing a pebble into a lake. it's gone, you can never get it back. but the ripples are still there, and they spread out, further and further, until they cover the entire surface. there's no way to stop them.
if you say anything, even one tiny little comment, that's it. contrary to what many people believe, you can never simply "take back" what you said. you said it, and that's it. the words are gone. but the effects of your words ripple throughout the world, with absolutely no way to stop them.
this can be for good or for bad. you say something constructive, and the positive response from those few simple utterances can last a lifetime.
but...
if you say something hurtful, even just as a joke, the destruction can be devastating.
every single word that you say holds tremendous power. never underestimate it. i know this from experience.
and one last point:
"sticks and stones can break my bones, but words can never hurt me." I'm sure you've all heard this phrase before. it is the absolute biggest lie on the face of the planet.
