even her daughter marie-valerie wrote it in her diary..
I got the diary so i will look for the text in it..
i will write it here(translated to english):
3. December 1888:
Mama(sisi) thinks the christmas present is beautifull. We talked about all kinds of things, when Papa(franz joseph)came in the room and asked me(marie valerie), if i cried about the terrible suprise , that mama had A anchor on her shoulder, what i think is so original and not so horrible. " oh no", sighed mama, "i rather cried about an other suprise".
papa: "well?". Mama: "she(marie valerie)wants to tell Franz( franz salvator), that he her chosen one is.".
Papa in a short manner : "What does that mean?"...
and so it goes on...
