DH and I live in a cul de and our neighbour has taken to blocking us in and out our driveway.
It started when they were having an extension built and they couldn’t park their two vehicles on their driveway. Now he’s started parking his transit van most of the time in a way that means we either can’t get in or off our driveway.
We’ve spoken to them multiple times and they’re always very apologetic but it keeps happening.
Drove into the street today and he’d fucking done it again.
I noticed their drive way was empty so I parked my car length ways across it. God I know IBU but I am so fed up of them blocking us in and out.
The wife came to the door and asked me to move off their driveway and I said of course I’d move....as soon as the van blocking us out ours is moved. She said she coundnt as her husband was out.
And I know I’m going to be flamed but I politely told her that I’d move it as soon as we have our driveway access back and closed the door.
The husband was suddenly home within 10 minutes 
and I explained to him that, without exception, every time he blocks us in or out I will be parking on his driveway.
God I am so bloody angry. I have two young kids and I can hardly use my bloody driveway so have to traipse them up the street after parking a good distance from the house.
I also told him that the next time he blocks me in I’ll be phoning the police and will not be going to his door.
