As you know - may be!!- I'm very found the Princes of Asturias, but never can tell if, for instance that Letizia is unhappy.
She is exactly as all human beings and adults ones confronted in their private and professional life with a lot of difficulties - at the opposite of those we think that a prince or a princess's life is a golden one whithout no problem- Yes, the Princess is under the terrible shock of the loose of her sister - as every body in the same case- but, and it's her one of major qualities, she has a great sens of her duties and fonctions and she live in a very affectionate area in wich she is receiving a lot of love but also - it's so important to - she is giving a lot of love.
Said that she is "Unhappy" is a tittle for tabloids, but think she can be sad time by time and now, perhaps, very often because the disparition of Erika is more realistic and coorespond totally to the great personnality and to the no egoistic character of the Princess.
She is not only the wife of a Prince, the mother of an Infanta ( sooner two) but also Princess of Asturias and by the way very concerned by all the spaniards among them some are very and truly and deeply unhappy.
I think that this transcendance is totally lived by the Princess of Asturias with all the consequences for herself, even it's not very easy all days long.
