New house. New build development still in progress. Each house will eventually have two parking space. It is currently still a building site and builders vehicles on site parking wherever every day. Lorries requiring access. No defined parking spaces yet.
So my house is a semi. The rear looks out onto the building site. Its a small development and next door are the end of the site. So no one needs past their house to get anywhere, its just a wall. When i moved in i happened to break my foot on the same day so my dad brought my car over. Neighbour was parked with the side of his car parallel to his back fence which is just a straight line with my fence, the front of his car parallel with the wall that is the boundary for the site. There was a space beside his car so my dad parked my car there and it made sense to me as it meant neighbour didnt have to manoeuvre round my car to get out which he would have to do if i parked behind his car parallel to my fence as he had parked. When my guests arrived they parked behind my car so not blocking in neighbour. This has been happening for 4 weeks. I am finally driving again and the first time i took my car out I came back to neighbour having moved his car so it was parked diagonally across the two spaces his and mine were previously occupying with the front of his car directed towards his fence. I took it as a hint i wasnt to park there again so i parked with the rear of my car against my fence as his car seemed to be indicating thats what should be happening. Today i come home and neighbour has moved his car back to the way it originally was and there was a builder's vehicle with trailer in the space next to him meaning if i parked in my new method it would be a impossible for him to get out so i pulled up behind his car and parked parallel with my fence. As i was going in to the house he came out and said that he parked the way he had the other night (diagonally) because when the site is completed thats how the spaces will be. Each house will have two spaces for cars to park with front of car facing fence. And that he didnt want any of his guests to be blocking me in. This is fine, i have no problem with this, however the site is currently a third of the size it will be, there are site guards up blocking off what will be our driveways, there are builders vehicles and lorries in every day and what this idiot hasnt seemed to realise is that if my guests park the way he is indicating i should park (parellel to fence) then my guests will be blocking him in! Whereas if i park beside him his guest can park behind him and block no-one in and mine can do the same. Never mind the fact that as soon as the builders are back in the morning they will use that empty space beside his car, my car will be behind his and he will be blocked in. Anyway, i've done what ive been told and parked behind him.
There is no AIBU there is there? 
Ok AIBU to think my neighbour is an idiot and does he really think that i'm going to be parking in his drive when the site is finished?
