Are there any women on this forum that would invite a stranger, albeit one she MIGHT recognise, into their home whilst they were alone, at night ? I know I would not.
I'd like to say that I wouldn't and no two ways about it, but you know what? I'm not sure I can really say I wouldn't with 100% certainty. It depends on why they'd be at my door, and on how much their arrival would throw me off balance. If a neighbour knocked and brought back my cat, then made small talk about the cat or something similar, I might ask if they want a cup of tea if it's bitterly cold out there. I don't know for sure, but I couldn't say for sure that I wouldn't. A complete stranger, no. Do you know what I mean?
But I certainly wouldn't 'beckon' anyone in.
Personally, I don't believe JY did, either. I think it's possible that she came home, took off her coat and her boots, dumped her backpack, washed her hands, turned on the oven and poured the cider. Then, there was a knock on the door. Perhaps a voice, "It's V. from next door, I've brought your cat." Whatever excuse he might have used if it wasn't the cat. Then, when she opened the door (possibly after checking through the window or the spy-hole), he either made neighbourly small talk, perhaps about the cat, perhaps warning her about the icy path or pavement, and she may or may not have asked him to step in out of the cold before he attacked her; or he attacked her as soon as she opened the door. For some reason I think the attack occurred in the hall, very soon after she came home and very very soon after she opened the door, and she never invited him into the kitchen, nor did she beckon him in as he says. If he went to the kitchen (and bedroom and anywhere else), I think it was after the attack. I don't know if this is what happened, and I can't prove it. But, like someone said before (I think it may have been Otto), I think he'd decided he was going to enter her life before he knocked on her door. I don't know why or how, or how he'd thought it was going to work. She didn't react the way he'd imagined she would - she got scared, screamed, resisted. He strangled her. Perhaps he didn't intend to strangle her before he knocked, but I think he intended to do something else, make a pass at her, as he put it, whatever exactly that meant to him. It was either getting what he wanted (rape?) or killing her after she'd opened the door.
As I said, I can't prove it. My speculations only.
