HAHAHAHAHAHAHAHA! What a cheeky fucker she is! NO WAY @Rallentanda
Not the same, but I had an American penpal in the early 1990s (didn't have DC at the time, but was engaged to be married to my now DH,) and we exchanged letters (old fashioned snail mail!) for about 4-5 months, maybe 6 letters each, and we exchanged several telephone calls. She was sooooo totally excited to speak to a Brit!
Anyway, she rang this one day, and said 'guess what hun? I'm coming to the UK for three weeks in 3 months time, so we can finally meet!' ('Finally,' after just 4-5 months of being penpals?!) I said 'oh OK, right, nice one, where are you staying? We will have to arrange to meet up one of the days.' She said 'where am I staying? Where d'ya think sweetie? With you of course, in your 2 bedroom flat, you have a spare bedroom right?' (She was coming with her boyfriend!)
I was blindsided! I said 'well the second room isn't really a bedroom, it's just a 6 X 8 feet cupboard that has the boiler in it, and we have a little washing line in there, and keep stuff in there, there's not even a bed.' She said 'but YOU said it was a 2 bedroom flat!' I said, 'well, I don't remember saying that.' (Maybe I did I don't know, but the fucking cheek of her to think she can book a THREE week trip to England, and stay with me! I had only been writing to her for 4-5 months!)
She said she had been looking forward to being shown around Scotland and Wales and London and The Lake District (I lived in the West Midlands at the time, so NONE of them were nearby.) I said 'that wouldn't have happened anyway, as I wouldn't have got enough time off work or been able to afford all of that.' She said 'very disappointing. See ya.' Then she hung up and never contacted me again. To this day I am convinced that she was just using me (made me her penpal) to have a place to stay, and a chapperone!
tl;dr, a similar thing happened with a penpal from Nigeria. But she didn't tell me she was coming. She just turned up with 2 suitcases at mine and DH's flat (this was about 3 months later,) ready to stay with us. I had been writing to her for about 9 months. Maybe 7 or 8 letters each ... As luck would have it, me and DH had gone to North Wales on a caravan holiday THAT MORNING, about 2 hours before she got there, and were away for 10 days. The only door to the flat was solidly locked up (a big upvc safety door,) with no way in, as it was a second floor flat. So she couldn't gain access through a window.
The neighbour told her that we had just left and wouldn't be back for 10 days. She told me (when I got back) that she looked crestfallen, and asked if she could stay with her. My neighbour said no of course. This penpal stayed outside the flat/in the communal garden all day and overnight too (lay on one of the benches,) just in case my neighbour was lying. Next day she left, and I have no idea where she went/stayed. Again, this penpal never wrote to me again. Just using me. The cheek of turning up without warning though! 😬
