Have fun nay
what was the headmasters reason to say no? it's part of her culture, I'm having a hard time finding a reason that would offset the importance of that
Good question. Particularly when she says it is a spiritual/religious thing... and if other religions were not being denied.
If you were Christian, you could probably wear a cross... I wonder if there WERE Christians wearing crosses at the graduation in which case, I'd say it was discriminatory. But if everyone's religious/spiritual articles are denied, then it wouldn't be just picking out her particular life philosophy/cultural heritage.
I think I'd have to know if it was a case of it being 'just her' or everyone really wasn't allowed to represent important religious and cultural differences.
