Believe me, sometimes when I'm hurt by painful words which I know were directed to me, I think I'm not capable enough to trust anyone around me. Even now, I don't think I do. Violence is painful, but there are words that are more painful and that is a different story.
Although I feel that way sometimes, I know not everyone is like that. I sill believe in humanity. If the people can't show an example of that, I will be the one. Until the day that I can show that, I'll endure everything till that day comes.
I think that is why I became a writer also. Maybe you can relate to some on my blog @adailydose.
Keep insipiring others. ^^
No real defense against those words except for dealing with them. At some point, we all struggle with sounds that are more like noise. But I think people need to acknowledge that struggle as their own weakness. Of course, some people are just saying things to be a jerk, and I'm not talking about that situation.
Those words hurts more when they come from people close to your heart.
