On throwing water

I was waiting for someone outside my building. Like most roads in mumbai, this too filled with potholes. Intelligently, I chose a spot where no water could be splashed. Waiting, seeing the splashes and everything, a thought hit me, Doesn’t this water spilling hit the car too?

Doesn’t this spoil the car too?

Why don’t we (including me) not realize that every negative thing we do for others comes back to us?
