I too would say it depends on the relationship, personal, business, neighbours, family?
Anyhow I had a win with the narc who used to live next door. Ended up lodging a police report on his continual tresspass on our rural property with his camera, DH told him to FO a couple of times, but he kept jumping the fence or gate.
Anyhow the police turned up and he got such a fright, told people (who hadn't even seen the police) that I had dobbed him in for growing dope, which is strange considering their property had been up for sale with several open homes in the weeks prior. Duh.
The new neighbours are lovely but showed us in the inside of the shed, it has pictures of us and our dogs on the walls! Apparently there were other photos of other random things the new people got rid of, but they wanted us to see those.
If I see him around again I will call the police and have him up for stalking. But the police report/record is there now and he didn't expect that at all...
