So, came home today to find new NDN having work done. However, the builders are using the side of my garage wall to lean their woodworking equipment on to cut their wood and sitting under my window having a break and a fag. On my driveway. They can clearly see I'm sitting there. To explain, we are 2 detached houses, with front monobloc driveways next to each other. They access their back garden via the side, where the driveways meet, which is quite narrow. We have an extension at this side, with a window overlooking our drive. We access our back garden via the other side. As we have different monobloc it is clear to see which area belongs to who. They have piled the debris from the other house along their side access and so are using ours to do the work and sit smoking. This was bad enough, but their female "supervisor" came out and gave them seats to sit on my driveway, under my window!! Final straw. I went out and asked them to not use my property. She was so passive aggressive, asking if she was allowed to "step" on my side. Was I unreasonable to ask them to move themselves and their woodworking equipment? I did so politely, but I am so angry. If they had asked I would have said yes, it's really no big deal. It was the attitude, especially hers. She was virtually mocking me. Am I over reacting??
