I was letting the cat out via the window today (flat, no cat flap) & was wearing a baggy t-shirt & knickers, as it's lovely hot day. Low window so might be able to see I was only in that. Anyway, I was shutting window a guy walked past, did a double take & stopped, staring. I put the blinds back down & thought just a nosey passerby. 5mins later the front doorbell went. I didn't answer, thinking it was prob for next door . Then a knock on my window, so sighing, I found my shorts & answered door. It was same guy. He said 'is this Carol's house'? I said no & hurriedly shut door. I'm worried now as the 2 other flats keep leaving the main door on the latch despite discussions re safety . I do have a CC TV sticker & fake camera by my window but still feel rattled. I've seen him since, with a woman, walking up the other side of the road, and so worried i'll come across him again. He's built like a tank & well over 6feet so hard to miss: & he obv wasn't bothered by the v obvious CC TV stuff.
