okay well yesterday i got my ear cartilage pierced.
i have a silver barbell and isnt too noticable when i cover it with hair.

my question is, if a teacher sees it, and i have a note from my parents allowing me to have it, can they tell me to take it out?

and i need help with the note aswell... just to make sure it works well and the teachers will be fine with it.
i was thinking among the lines of:

to whom it may concern,
(name) has had her ear pierced on sunday the 7th of june, 2009. As part of the healing process, she has been told to wear a silver barbell, as she could not get her ear pierced with a clear stud. (name) cannot take it out for another 7 weeks, so please excuse her from any issues concerning it. She will be able to wear a clear stud from term 3, week 4.

do you think i could get away with that? or will they tell me to take it out as part of school code? this is really important to me. it cost $90 2 get it done and i dont want to take it out and have to either wait until school holidays.

thanks!!!
