Unlucky....

So unlucky!
My car hit someone's car by the bumper.
It is because my dad parks the car with the wrong gear.
And I have no idea what did my mum do in the car.
After my dad and I get down from the car.
The car moves forwards and hits the car in front.
Have to pay RM300.
My mum blames my dad.
My dad blames my mum.
Dad blames me for insisting to check the leaking pipe.
Sigh.......
Who and What should I blame?
