NDN is a man in his late thirties who moved back in with his parents a few years ago. Parents have lived here for 30 years. We get on fine with them when we see them. We just say hi and have a small bit of chit chat and then get on our way. Since we moved in (2 and half years ago) the son has been smoking weed, and it did annoy me a bit then, but I just got on with it. However, it is really bugging me now. WIBU to report him? Truthfully, I’m worried that if I report him, although it would be anonymous, I think it would be pretty obvious it was me, and I don’t want to be worried about them being petty or nasty towards me back, even though I’m not the one smoking an illegal drug in the middle of the day in the garden.
