"TIL that French schools used to assign 'Le Symbole' to kids caught speaking minority languages (i.e. Breton, Occitan, Basque, etc). The only way to rid oneself of the symbol is to snitch on a fellow student. At the end of the day, the student with the symbol will receive some form of punishment."
Between the crosses, row on row
That mark our place; and in the sky
The larks, still bravely singing, fly
Scarce heard amid the guns below
We are the dead. Short days ago
We lived, felt dawn, saw sunset glow,
Loved and were loved, and now we lie
In Flanders fields.
