I'm going to tow my neighbor's car.
What makes you want to tow your neighbor's car?
It was parked in the middle of the road.
If you do find that you have issues with your neighbors when it comes to parking, speak to them, be polite and don't threaten them. Usually, these problems can be sorted out with a few carefully chosen polite words.
But why should I cool my temper when I'm mad huh?
Towing your neighbor's car is extreme and there's no reason for it if you haven't even tried talking to them about this. You'd better calm down and try to sort things out with your neighbor or things will be very unpleasant between you and them.
