In our close, we all seem to have a gentleman's agreement , that is that we all park in the same place every night. This has been the norm for the last 7 years so why should someone decide to be awkward suddenly?
Because he is a twit.
Park your MTB on his roof !!!
Cul-de-sac person here, but everyone usually parks on drives/outside house. Our neighbour spent a while parking on the visitor space with his van right next to our land, so we had no view from the kitchen. Didn't say owt, but he now parks on the huge paved front area outside his house. He is a bit of a twit, built a massive 'breeze block' 'wendy house' (for his pain in the aris son) in his back garden - we can't see it, but his direct neighbours can. They are furious.
I suspect it was his snotty missus that didn't want his van outside their house. Appart from the fact their extensive block paving is weed ridden.
There is always one. Either ignore, or go in guns blazing. Some folk are nutters and will damage your property though, out of spite.
