Bit of a strange one. Sorry for the super long post. Just hoping to get some perspective as not sure if I'm over reacting and been a paranoid weirdo🙈. I purchased my home 15 years ago and in terms of neighbours they're all a good bunch, that was until 6 months ago when a couple started renting the house directly behind mine. We live in town houses with smallish patio type gardens so not a great deal of privacy but there are trees blocking the view of all but this one neighbour in particular.
The new neighbours spend alot of time outside smoking cannabis. They line their deck chairs up against their house, so they are spending hours just staring up at my house. The smell is awfull thay sometimes I've had to keep my kids windows shut even in 35° heat but I've turned a blind eye for an easy life.The windows that they can see into are my kitchen, kids bedrooms and bathroom. They litterally sit, outside for hours day and night just watching, staring up and in with a joint in their hand.
On numerous occasions I've noticed one of them watching me in the garden from one of their upstairs windows. When I have that feeling I turn around and see their curtains move as if someones jumped out of the way. I do have privacy glass in the bathroom but nothing in the kids room. It made me feel quite uneasy having them looking up when my kids were in the bath but as it's been summer and it's nice to have a bit of natural light, rather than drawing the blinds I invested in an extra layer of frosted privacy film so although you can see slight silhouette there's no detail. When the dark nights draw in and I have lights on I always shut the blinds anyway. I still convinced myself at this point that I was imaging the prying eyes and just been paranoid.
Today I noticed her watching me while I was doing the dishes in the kitchen so drew the blinds. She saw me do this and it's obviously enraged her as about an hour later she pushed and hand written note through my door. She went onto say in the note that she wants to let me know that my privacy glass in the bathroom isn't even private. She says she's been looking up and can see my whole family bathing. She went onto say that she was telling me for the sake of my privacy (Like she cares about privacy). She even told me that she knows where my bath is in the bathroom. To pin point this she's obviously spent time staring through my window when it's open. Now if this was genuinely a concerned neighbour giving me the heads up that my bathroom wasnt private I would take it as a kind tip off but shes litterally made no attempt to inform me of this and shes litterally spent 6 months happily watching us, and only once I've finally blocked her view, she's written me a snappy note. To be honest I feel a bit violated, not just for me but also my young children. Shes basically just openly admitted that she has been watching us in a letter😖. I don't really know what to do from here. Should I appraoch her? Report it incase its escalates? I feel like a hermit in my own own as I'm even shutting my blinds in the daytime now.
