I go to a school on the grounds of a Catholic monastery, and since we have mandatory masses on some Catholic holidays (Christmas, Easter, Ash Wednesday...), yes, I got ash on my hair.
You go to a high school with mandatory Catholic masses ?
WTF ?
I thought this stuff stops at elementary school, after first communion ("Erstkommunion").
At least that's how it worked here. But the "Holy Land" Tyrol might be different ...
It's a private school, used to be run by the monastery. Up till today, some relicts have remained (mandatory Latin from grade 9 onwards, crosses in classes, and of course, masses)
