I was having brunch with an American friend when two American tourists came in asking for directions. We spoke to them kindly, they thanked us, and as we parted ways, my friend whispered under her breath "They're so loud, these Americans."
Actually, the only thing that wasn't stolen at the Louvre's Apollo Gallery is the Regent Diamond, figure no one would take it because something to do with a curse.
I've also found that the two thieves were leaving for Algeria, thanks of a trace of DNA evidence recovered from a helmet and their past in burglary cases according to the police.
