My dad is flying off the pan now.
Terrifying. But luckily it's not me he's angry with, it's my brother.
I totally understand why.

People humiliate or scold people through Facebook.
Facebook is not designed to be used like this.
Don't be overwhelmed by your anger and lost your rational.
Facebook is a very dangerous weapon.
Once you post something, the whole world knows.
If you humiliate a person, that particular person will not be able to lift his head ever again.
Why will anyone be so cruel?
I totally patronize that kind of people.
Are you so timid that you can't ambush him yourself?
Tell him what infuriate you so much face to face.
That's gentleman's way.
Scolding through facebook? That's coward's way.
