a friend of mine has developed an interest in witchcraft at age 20 after having grown up in a strict catholic household. my big concern is what her living arrangements will be like if her parents find out. I sent her a facebook message. I hope she would still have a home.
I personally feel that you're friend is at an age where their parents can't have a say in their religious life. Time to move out already.
Hopefully, when/if your friend's parents find out, they'll understand that part of the growing up process means testing one's own wings - trying on new belief systems to see if they fit - and won't get too bent out of shape over it.
she has a right to worship and believe as she pleases.. things have a way of working themselves out..
