So there's been a car parked just outside between mine and my next door neighbours house all day, didn't think too much of it until he was still there later this evening up until about 15 minutes ago, he was sat with the headlights on for hours until he seen me obviously looking out the window and then turned them off. It's a very quiet side street and my next door neighbour doesn't know who this either and also finding it odd. I went back into my sons room and peeped out a tiny corner of the window (definitely wouldn't be able to see me looking) to see if he was still there and just caught him finally get out of the car, and then take a picture with his flash on at my house. It was a youngish guy probably in his early 20's in it, I panicked a bit and opened the bathroom window to ask if I could help and he looked back and walked off. Just checked the reg plate and it is invalid.
Am I being ridiculous to be a bit worried about this? My partner (who mostly works away and is often just me and my 2 year old hence worries me a bit more) has just told me not to worry and it's probably nothing, which I might be more inclined to agree with had I not caught him take photos.
