A car we've never seen before (presumably a neighbors guest) is parked right in front of our house on the road, right up to the edge of our driveway. As a result my partner couldn't get his car in the driveway, and had to park in the carpark right next to our end terraced house. For the sake of three meters I don't understand why the strange car couldn't park in the carpark. It's also bin day, and as a result of a lot of arguing and complaints to the council (2016 was the summer of the wheelie bin wars, more boring than it sounds) all bins will only be collected if directly outside their corresponding houses and easily accessed (I.e not behind a parked car) so we have had to block our own drive way with bins. Would I be unreasonable to go back out and block the strange car in with the bins for being too lazy to park in the carpark literally at the other side of my drive?
