What an extraordinary thread - and what a brass neck!
one acquaintance pushed back and asked to stay with us at the beginning of September. I told her that this would not be possible, especially as we have a very tight deadline and will be working flat out to finish a commission. DH and I are self-employed craftspeople and sometimes we do work all day and most of the night to finish pieces and the DC stay at their grandparents during that last push. Not heard back from the acquaintance since July even though she clearly read my WhatsApp message.
She will (pretend to) have chosen to interpret this as you saying how terribly sad that you won't be free to actively host her and pander to her every whim as a guest, however, she "understands that you're very busy, she won't be any trouble at all and will happily look after herself - you'll hardly know that she's even there".
All lies, of course, as demonstrated by the fact that she didn't even bother to reply to your original response and give you a chance to spell out the obvious to her - and if you had let her cross the threshold, she'd fully demand to be waited on hand and foot, in spite of her 'reassurances' - but that's what I fully reckon was going to be her MO.
"Oh, I didn't want you to worry unnecessarily in advance about looking after me when I come, there's no need to go to any trouble at all - it will just be lovely to spend some time staying for free in your house and eating all your food with you if you do get any chance for a quick break even though it wouldn't be any kind of break if you have to entertain me."
Always going from the pov that you want them to come as much as they want a freebie, so they 'find a solution' to 'your' problem.
In fact, she may well try to capitalise on the fact that you'll both be in your work area for so much of the time that your actual living area will be going unused, which would be 'such a waste,' so she'll do a bit of dusting and hoovering and keep it 'fresh' for you she won't, so that everybody wins!
CF's thrive on 'misunderstandings' that they always engineer and manipulate to suit them in getting what they want. I can't for the life of me understand how anybody could enjoy forcibly staying with people who very clearly don't want them to be there. Wouldn't it just be so very awkward indeed? I suppose it's all just water off a duck's back to them if it means they get a free holiday and/or save a wad of cash.
