This reminds me of when a neighbor reported to the landlord that we were smoking weed indoors. She claimed she could smell it in her own apartment. We weren’t (and weed is legal where I live, so it’s a moot point.) When the landlord came around, we let him come in and smell our apartment. He found nothing.

So we suggested that the landlord go smell HER (the narc’s) apartment to confirm how bad the smell is. Guess what? She refused to let him in.

If she ever attempts to complain again, the procedure now will be to investigate her apartment first. If she refuses, we won’t be bothered. So yeah.
