Surprisingly, and understandable for the people who didn't think the Spanish monarchy could survive JC's scandals, it's healthier than been in decades.
When I was young, I used to be so jealous of the Nordic countries. They had kings and queens having a "normal" life by mixing with their people - they could walk, shop or go to a movie like everyone else. Many of us in Spain thought it'd be impossible to see that kind of monarchy in our country. And we were wrong.
It's a bit incredible how things have changed in a few short decades, starting with me not feeling jealous anymore

Felipe and Letizia have transformed how the monarchy is generally now perceived in Spain - they have an institutional role to fulfil but they can go shopping, have fun with their friends and be part of society even if they need bodyguards.
Letizia is often seen shopping for books, vegetables or just browsing shops in Madrid. Felipe goes shopping in El Corte Ingles, where most of Madrid go shopping.
They've normalised and connected the royal institution to the people.
