Actually, JC's escapades were pretty well known by all Spaniards, I can almost give you a chronological list of his mistresses, we all know who they are, there are even pictures of him with them.
Hell, we even saw him naked in a boat once
For Sofía, she's always been terribly reserved in her "personal" life but we also know she has like 3 friends because she understood how important it was to keep the Crown safe (like QEII has done), yet we see pics of her in London with her sister, in Greece with Tino & Co, in Geneva visiting Cristina & Co, we always saw pictures of her visiting her children when they were studying abroad, etc.
With F&L and their children, a LOT of the time we don't know where they spend their holidays outside of Spain, they have a perfectly great place in Marivent to promote tourism and spend their holidays, they don't even have to go out every day, the place is pretty private and they can sunbath and whatnot there; if they want to leave, at least let people know where they are, because after all we're paying for that and if we're paying for the keeping of a huge complex in Mallorca, do we also have to pay for their "foreign" holidays?
Would it kill them to be like the Belgians for example, from whom we always know if they are in France, in Spain, in Italy, hell, we knew they were in India at one point. A couple of pictures and the paps will leave them alone the rest of the way. (And they don't have a Marivent or a Balmoral, a place where they always spend their holidays).
It's basic PR.
And what do we mean with the 9-5 comment? Not that you NEVER have a break but that if you're in public, you keep yourself together unless it's like a funeral or something, you don't throw tantrums, touch your children endlessly to the point of making everyone desperate, slap hands away or kick car doors open because you're mad at something.
We all have to behave in our day jobs, why can't she do the same? Specially since her job is basically PR and image.
