Posted in internet safety as couldn't find RL safety thread.
Last night at 8ish we noticed a neighbour from the house converted into six flats opposite standing topless (couldn't see his bottom half) at his window and it looked like he was starring into our house. We have three kids and the neighbours either side of us both have kids too.
My husband stared at him for a minute and he went say, but when we looked up a few minutes later he was there again so we got up and closed the curtains, he went away as my husband approached the window to do so.
It's not a big road in between the houses so he was definitely looking at our or the neighbours house. There is a sea view in the opposite direction so there is something to look at if you wanted to look out of the window.
What should we do? Approach him if he does it again? Take picture to show police (does this make US creepy!) or ignore it?
