Shoes out of the window

In Holland when students have finished their last exams and have passed them they hang their rucksack or whatever it was they carried their schoolstuff in out of the window, preferably from the flagpole. In Belgium apparently students hang their shoes from the window (or throw them over trees or even electricity lines) !

This pair must/could have been belonging to one of the students who had second chance exams this past month, as schools starts again this Monday ! Taken from the passenger seat in the car on the way home from another walk in the woods. Hope you're having a good weekend !
