I've had this happen a few times actually, I'm quiet trusting by nature and often don't realise how odd a situation was until later when I tell some else about, my dp swears its a minimal I haven't been murdered or whatever as I never seem to have the same boundaries or alarm bells as others.
There's two situations in particular that I honestly believe some sort of 6th sense kicked in .... the first was a neighbour, he worked closely with local sports club, eg he manage the playing grounds and other stuff... he's older than my parents, and was seen as an upstanding pillar of community type, everyone knew him and he was "lovely"... as a kid an easy way to make money is to sell programs at the matches in the same grounds he worked on, alot of my friends would do it at the weekend ... anyway I asked him one day if I could sell programs too and he was all cheerful and "absolutely" and said I could get a ride with him ... all fine, until the day came and I got in his car, as soon as we pulled off I felt so fucking uncomfortable/uneasy/sickly even ... he was way too nice/overly friendly, at the grounds I met a friend and me and her kind of just wondered around the building (going above the changing rooms etc.) It was kinda creepy, broad daylight but very eerie I literally took off, running down the flight of stairs out the door and over the the spectators entrance, I've no idea why, I waited for people to start showing up for match (I was super early because of who I got a lift with) I desperately wanted to go home I felt like crying but I couldn't explain why... I didn't go back into the building, after match I still had to hang on a couple of hours for the same person to give me a lift home .... I felt sickly again in his car, when we pulled over at my house, he pulled out a note (payment) and when handing it to me put his other hand on my knee and I left out of that car as fast as I could and made excuses to not go again the following weekend, I never wanted to be anywhere near him or that place ever again, I was about 12/13 at the time, as I got older I kept referring to him as that pervert and peado, my mum used to give out to me for it thinking I was just being an ignorant nasty teen as in reality nothing bad had happened, he was perfectly nice & was so busy I only got a couple of glances of him while I was at the grounds but I just could shake the feeling, I had mentioned it to a few others (my age group) at the time that I thought he was creepy and they legit called him a peado that he look at them weird or for too long and just too nice .... any way I'm all grown up now in my 30's, hot a call a few years ago from mam asking if insert name ever touched me I was like ew know why? She's like well you always called him a peado and I said yeah must of been so angsty teen rebellion shit but no he never gave me any reason to call him that & she tells to turn on the news, he was arrested for one of the biggest child abuse cases in the country along with a number of other men from the town operating out of that sports ground, some of the details have emerged and the abuse was sickening, violent & humiliating.. my mum is still convinced he must of done something or I seen something for me to suddenly take an instant revulsion to him but honestly he did nothing and apart from feeling uneasy the day I spent working for him was completely normal...
2nd story was much later (I was 23, living in same town I am now which is over 100 miles from home) was looking for a new rental and asked my letting agent who worked on behalf of my landlord if he could find me somewhere new... just side not I always found this letting agent a little too friendly or comfortable but he was an older man my guess mid sixties & seemed quite harmless, he rang me up and told me he had a letting he thinks would be perfect for me, I asked for address and he says he'll just come pick me up as he knew I didn't drive and would save me a taxi, so he comes I get in the car and instantly feel weird and suddenly overly aware I had willingly got into this man's car not knowing where I'm going, so I'm trying to be friendly but intently watching were we were going trying to guess by the rout, we end up in a housing estate inwas familiar with, and pull up to a house ... I remember thinking as we went inside how it didn't look like a rental, had bright red walls in hallways (mess paint job) made hall look small/claustrophobic... living room to left was dark/musky everywhere was rather dishevelled and unclean we didn't go into living room, just straight down hall to kitchen, it was brighter but very much "lived in" very untidy/dirty dishes in sink, ashtray full, yellow tinged white paint fittings/fixtures just gross... he opened backdoor and in walks chickens 🐔 he points to garden to show me their coup and a veg patch says he's been keeping chickens years, fucking alarm bells when I realised I was in this man's dark,dirty,creepy home ... so I'm edging back from the backdoor and towards the kitchen door to hallways slowly while making small talk, very aware front door was closed I hadn't noticed he closed it behind us, the overwhelming smell of stale smoke was so disgusting, so I decide to play dumb but assertive and I'm like "ah sure it's a grand house you have, just you here by yourself?" And started practically marching to the front door and he's coming up quickly behind me with a sob storey bout his wife leaving him a few years back he gets in front of me and one hand gestures to the dirty living room, for me to go in, so without moving my feet I do an over exaggerated leaning glance and the living room and I'm like oh that's nice but I need to get home to my baby (she was 3 y/o with her dad ) I said I hadn't long with the babysitter and I didn't know I'd be going to his house first so had told her I'd be 15/20 mins tops as I told her I was going with you to view a house (was hoping he would realise some one knew I was with him, I was honestly fucking terrified at this stage) he then tells me his moving out and letting the house and thought I'd be interested in it for its location so I'm like it's a bit big for me and the garden would need maintenance etc. I wouldn't be able yada yada.. so he grabs my elbow and says do you want to see upstairs 4 big bedrooms and large bathroom, saying he knew I was a single mum and I could have the place for a steal, so I open the front door and was washed with an overwhelming feeling of relief walking out and seeing the next door neighbour in their garden, so I loudly say that the house really isn't for me ... but anyway now I have to get back into the car as I didn't no where I was and needed to go home .... we drive and then pull off into a other estate, and at end of a cul de sack there was this super small "house" on the back of a different property ... we get out and he's like I just wanna show you this real quick and walks towards this tiny like garage conversion thing and I'm like in my head I'm not fucking going in there with this man, like fuck no... luckily I knew this area well & wasn't far from home so I tell him I can't go in as I said the babysitter is waiting and Im just gonna walk home because there was a shortcut through the park at entrance of this estate and would bring me to mine and I wanted to stop at shop etc. He seemed genuinely offended but I felt so unsafe... I've literally no idea if he meant me harm but I didn't feel comfortable even having him as a letting agent anymore so I quickly moved from the house I was in to avoid having to see him again.. found out later that the man had a loud of legal disputes with tennents for letting himself into there homes with consent or even knowledge... he had done that to me too but I just started leaving my key in the door so his key couldn't be used... he apparently walked into a tennents bedroom while she was in shower in the ensure, she walked out in a towel and he was just there, she screamed murder and pressed charges .... I wish I had of listened to that gut feeling at moment I first got in his car, I don't know if meantbany harm to me, maybe he has boundary issues or whatever but when I stepped into his house, not knowing it was his house, I was overcome with dread like some awfully bad was going to happen to me if I didn't get myself out ... if anyone's wondering why I didn't, this man was old but he was one of those big friendly giant types, I'm 5'3 & weigh 7 stone, he was about 6' 2 and built/stocky huge hands.. his friendly demeanor suddenly became very menacing, I suddenly realised just how vulnerable I was. Some people I've told this too think I did the right thing getting out/walking home while others think I was being a bit dramatic, they agreed walking home cause I was uncomfortable was the right thing to do but insists I was uncomfortable because I became paranoid for no reason because he didn't do anything apart from try convince to rent from him.
