Yes!! This is exactly what I thought. Mine was a book club choice too, which is why I even bothered reading past the bit at the beginning where All The World Is Against Us, culminating in the death of the (ancient and diseased) pet sheep. I remember being so annoyed by this that I called out to DH, "Oh for God's sake, now even the bloody sheep has died!"
Luckily my book club was much less enthusiastic about it than yours seems to have been, although they did enjoy the nature bits.
So funny when you think about her whinging about not being given free tea and scones by a small local cafe - I guess that must have seemed like a small ask after helping yourself to tens of thousands of pounds from your ex-employer!
There was certainly a huge sense of entitlement. The world really did owe them a living, in the house and surroundings of their choice, with tea and scones on tap. Regardless of the problems caused by their own terrible decisionmaking. Even in her own version, it was just breathtaking how badly they messed up. Complaining about the cold after they bought inadequate camping stuff. Complaining about the husband not having medication after they failed to organise it properly. Complaining about being ripped off in some vague way by a friend whom apparently they had entrusted with all their money with zero due diligence - I remember thinking, "Surely nobody could really be that dumb," and actually it seems there was good reason to be suspicious of that story!
It's quite something when you are telling your own story in your own words (and, as it turns out, lying and making stuff up as you please) and you still come across as awful.
