Based on the excerpts, which admittedly have been quickly translated from Spanish, the whole thing reads like a spoof.
Harry comes across as dumb. I mean Harold landing with his arse in the dog bowl, getting his bottom spanked by a mature lady in the field behind the pub, oversharing on his penile frost bite and saying he is not embarrassed about killing 25 Afghans chess figures while trying to justify why Meg is using sexist language and bullying 3 year old Charlotte into not wearing tights. It's all absurd.
I hope Carol, Pippa and Kate have a thorough laugh about his brain dump. It would be a shame if all this affected King Charles' or indeed William's health and I hope they are all getting the support they need.
