It happens. Many years ago my Dad was taking early snow and putting it against the house for insulation. There wasn't much snow, so he was scraping the neighbors drive.
The neighbor came out and game him hell saying, "Leave my snow alone."
In the spring, my Dad went out and was shovelling snow away from the house and threw some on the neighbors drive. He came out yelling. My Dad said he was just giving him back his snow.
