I do find Ian Wace's generosity fascinating. Back quite a few threads when it was first discussed, it was noted that he had bought a rather fabulous penthouse in New York with his girlfriend. I suspect he doesn't spend much time at the Northampton place, more likely dividing his time between NY, Scotland and possibly he has somewhere in London too. So it might have seemed no problem to say You can stay at my place in the country.... I wonder if Harry spun a line about it being temporary as Pa would be offering somewhere...
Next thing he's got squatters!
No doubt it's a very big house with lots of rooms but would you really want those too using your own bedroom/dressing room? Presumably not, but there must be other guest rooms with empty wardrobes available. Still - there's at least a nanny to accommodate plus security hanging around. Do Wace's staff do all the cleaning, laundry, meals???
From my research watching Superyacht chefs on YouTube, staff like nannies and security eat at different times to their employers. As a private person offering use of your home, his chef (if there is one hanging around there for the odd occasion he drops by) would probably expect to do regular mealtimes, not be running around at the beck and call of visiting staff, so that would probably be quite annoying.
I imagine a big estate has other houses for staff and perhaps he has one or two for guests - interesting he initially offered the main house, perhaps a guest house wasn't available at that time. Presumably this house is furnished.
They really are sofa surfing.
I'm sure the invasion of his privacy has been an unwelcome consequence of extending such a warm and generous offer to the H&Ms. How much longer will he remain generous hearted I wonder.
