Can another vehicle hit the rocker? How is this

I don't know when it happened but I realized that today. I don't remember hitting or rubbing it all over the place. It does not seem possible to rub this place unannounced because if I rub it unaware, it had to be drawn all along.
I have not understood how I wonder your opinion.
Thank you.

I think you may not have noticed a pit on the wood but not a pit.

That part is a little harder metal. Maybe it could be if the wheel of the car came, but I think it looks like rubbing on the sidewalk.

Well, there is a car traveling with so many places in the market. maybe the bumper of a vehicle with a flat bottom might have touched.

Probably you have rubbed on the sidewalk or something, there is no other explanation. If you do not remember the vehicle, and you do not remember it, you may not realize it. In jeep style or some connect etc traders, they put it on the side sills that are overflowing like this.

Cat is cat: P

Could the stone be crashed?

It seems to me as if I was rubbing slightly to the corner of the sidewalk when I was returning from the street or something.

I think those who took it very narrow when returning from an island or a corner street ..

did you entrust someone to you ??? :) :) :)
