Obviously nobody should have to do anything they don't want to with their own private property BUT I think there's room for a conversation about larger family homes.
I grew up in a big, crazy Georgian townhouse (located directly behind a chip shop, which is how my parents could afford it). It was legendary among our friends and family, there was always something happening and of course there were big changes over the decades with decor, updating etc.
Then my parents divorced, the house had to be sold, and they both now live in much smaller places, in one case a purpose built retirement flat.
We anticipated that this would be absolute hell for them both, but in fact after the dust had settled its actually brilliant. That old house was an unpredictable money pit and their new places are warm, safe and secure.
I hear people say 'oh we couldn't sell the house, it would be heartbreaking' but honestly, we've found that memories are about people, and that it's actually OK to leave a beloved family home with generations of history.
This was all through choice obviously but I would like to tell others about our experience, especially if it makes anyone's parent safer and more secure as they head towards old age.
