Some people just have no bloody idea of the effect of their reckless actions on others.
Ignorant, stupid assholes.

On a side note, if someone ever said he/she wanted to tell me what they feel about me, I will not choose to listen to it, if possible.
For it is also true that some things are better not said out and left to the imagining brain. And please do not call me an escapist for that idea. I'm just being realistic.
