I have a weird neighbour. Try to keep my distance as she rings my alarm bells every time I see her. Basic history is that we have objected to her planning application (wasn't being difficult - it just was huge and would've cut out all our light to one side of house)- which then got refused. Got up this morning to find she'd nailed a load of rotten wood pieces - all haphazard to our side of fence - behind her trellis. We have responsibility for the fence. Looks atrocious. WWYD. Tempted to get rid. Sorry - know this is petty in grand scheme of things but don't want to start a war. Do you think this is just her being a bit thoughtless or some sort of weird revenge?
