I drew these on my niece Julie’s student apron for the “student’s Saint Nicolas” (for a few days around the beginning of December, students from uni take that kind of aprons, decorate them and wander in the streets, gently asking for a few coins. If you don’t give them some, they can throw some flour at you. Nastier student can also crack an egg on you, throw a bit of beer, etc. They especially gather around their former schools. Let’s say they love to “attack” their former teachers :) )
After all that, they usually party, buying beverages with the coins they gathered.
