This is fun! He has so much interesting stuff, it reminds me of that party game where there are items on a tray and you have to memorise them and then have to remember what each of them was. Note the scissors and what might be a nail file/letter opener in a little leather holder on two of the pictures including the most recent. Why would he keep it on his desk? Maybe Maria gave it to him. I also wonder why he has his wallet on his desk? Most people keep theirs in their briefcase.
Yes, that second one I posted is def of his private apartment. If you go to the Picture and Video thread and look at the pix of him playing the piano, on one of them you can see on the wall almost out of sight, a small square picture - it looks identical with the one on the top right corner of the desk photo. A print of an antique world map.
I agree totally about the flowers thing. I love flowers very much and like to put them in little vases.
I'd think that some of his clutter may be things he's been given and is a bit sentimental about. The pen holder, for instance. As there is a bottle of ink and a rolling blotter on one picture, it indicates he prefers a fountain pen, so the pen holder, which probably holds a biro, is not much used. I may be wrong.
Incidentally, I think the older photo that I posted may be of the same CDF office, but before a re-decoration. It has those sheers at the window.
On Teresa's picture I don't see a crucifix, though it may be out of sight, but there is what may be an olive wood statue of St Joseph, the kind you get in the Holy Land.
