Expressions and other impossible tasks.

Expressions are hard, for me at least. I find it hard to say what I feel, or feel what I say. It's just not as easy as people say it is. You can sit there, speaking your mind the whole day and still limit your boundaries at the risk of hurting others. That's not a bad thing, neither is it a good thing. But it's something the human race has developed over time, and we do it subconciously because we don't want to hurt others. Someone will say something, something annoying, contraversial or offensive, but you'll suck it down. Then they'll say another, and you'll see red, but you do nothing because that is overeacting.
This will be the downfall of us. Expressions are important, too important. Because they show others how we feel. And if we feel angry but nobody realises it, how will they know how to stop? And if you crack and yell at them, is it really their fault? No, it's ours, and thats a hard thing to understand.
I go through these problems everyday, and I vent them through writing or listening or drawing. But that's not really enough and I need to learn how to express and vent through words without offending anyone.
Not as easy as you might imagine.
