Ok, I realize this is petty but....if a neighbor(or two different neighbors in my case) parked their car(or work van) in front of your house at times for days at a time, would that upset you?
I live on a small cul-de-sac street. Each house on this street has a 2 car garage and driveways that will hold at least 4 cars. The family directly across the street has 3 cars and the husband has a work van. They have so much stuff in their garage they never put a car in the garage but they never have more than 2 cars in their driveway at any time. The husband has apparently decided that he is going to start leaving his van parked on my side of the street directly in front of my house and parks it on Friday afternoons and leaves it there until he goes back to work on Mondays. Yet over the weekend as I said they have room for all of their vehicles in their driveway. I look at it like if you have a driveway then use it.
To be fair he isnt blocking anything and we have never crossed words with each other but some days I just laugh about it and then other days for some reason it honks me off and I think about parking my car in front of his house just to see what would happen.
