It just happened unintentionally

Dad stumbled upon a bad luck yest evening. He was driving to fetch sis from the school tat night before the tragedy took place.
They(sis and dad) came back home at 9.15pm, we(me and grandma) heard the stainless gate's being opened and locked voice. But it came weird when they didnt appear soon after the door-voice. I suspected there must be something happened outside.
I slithered downstair without any hurry, tried to steal a peek, observed wat have actually been transpired.

Oh,wat?!?
The car was hooked onto the stainless gate!! It cant even move forwards or backwards.
Once dad step on the clutch pedal to either move forward or backward, those sratch sound formed from the gate and the car was hurting. Heart pain-ing a lot. Especially dad. He dears his car as a precious, u know.
Actually there was another car parking too close to our place, hence dad revved the car abit nearer to the gate, he gauged the wrong calculation. He miscalculated the proximity of distance.
So on... it just happened unintentionally...
With the neighbour's assistance to manuever dad behind the steer, finally they got the car released. The tragedy ended up wif a 15cms long scratch scar on the car's right down bumper.
