Why do we always hurt the people closest to us?

Actually I have been wanting to blog about this. Yes, problem at my family and yes it's my bro.
Sometimes, I really dont know what goes in his mind, I'm really willing to pay $1mil to go inside his head and see what he really is thinking.

The actions that he did sometimes really put people around him off, not to mention cause distress and hurt to people around him.
I'm fucking sure he doesn't do that to his friends lor. So why family bears the brunt of it?
Is it because we are family? No matter what happens, we still forgive and move on, so it gives him the ground to behave like a fucking bastard?

I'm really so sad and felt that why I can no longer communicate with my bro. Sometimes, I wonder if who I'm talking to - is the real him or is it not?
I would tear and can't fall to sleep whenever I'm disturbed by his behaviour.
I know as a sister, I need to let him grow up and lead his adult life, but his actions put me off and pissed me off a lot.
Really at a loss. Adult talk doesn't seem to work.

I really dont know what else I can do.


P/S: I talked to bro just now, letting him know the frustations he is causing. I really hope that he understand what I'm saying and not closing his ears with invisible hands. Lets work this out together bro! U know I still luv luv you no matter what you do, jerk!!! heeee
