VENT!!!

my friend Joanna (she's fast turning into a not-friend, actually) is really pissing my off at the moment. She's belongs to the psycho Christian group at school (we are a state school, no one gives a damn about your beliefs) and is currently trying to convert our group of friends
she's selling badges with the group's logo on it (it's the school logo but with a cross in stead of a star). She tried to sell one to me and I'm like, "Are you kidding? I'm like the least likely person to buy one, you'd have more luck selling them to a brick wall."
I want to tell her I'll by one and wear it upside down!
It's not so much the Christian thing, she can delude herself if she wants, I don't care, but the fact that none of our group (less than half of which are actually Christian) can't have discussions about how weird religion and the nature of belief is anymore without her getting offended by the tiniest little things

ARGGHH!!! IT'S PISSING ME OFF!!!
