I found this heart of stone..
.. amidst a handful of other stones, a chestnut and a few sticks.
All those treasures were in a friend's car, in the "pocket" of the door.
A Danish child had left them there, then my friend bought the car (unaware of the present he was getting) and drove all the way from Aarhus to Sofia.
When he found the treasures, he thought they should stay where they are...
Only so, a few years later, far away from Aarhus, I can find this heart of stone and get it as a present..
