Self control is important sometimes

My dad's friend got into a fight.
Apparently it was over some double parking issue.

At first they started shouting at each other.
Then the shoving came,

And they started fighting.

It turns out the guy was the boss for air cond repair.
The guy took out his screwdriver and uhm..

Cucuk it into uncle's ear?
*Not exaggerating -__-
OUch.

Now he's laying in the hospital.
But seriously,
Uncle ah,
So old still want be hero for what?
Still want simply argue with people.
Aiyoooooh.
Bad example for his kids.
