After losing those items I started double and triple checking.
So far, I have found the doors unlocked 2 times.
Old age, I think
I am just happy I didn't put anything irreplaceable in that wallet. Only COPIES of driver's liscence and business card.
But who knows : If I have put in there the real driver liscence and real car registration card, this considerate thief might have left them behind. LOL
