Neighbour problem essentially. My neighnour had a fire/slash BBQ on my property, without my knowledge, fire brigade were called by another neighbour - they put it out.
They have left a huge mess - loads litter/soot stained concrete etc.
I don't want it to turn into something hideous. But I have been round, asked her to make sure the mess is cleaned up, and gently reminded her that the area is actually part of my property.
It is still a shit tip.
Not sure what to do next.
