Purplicious,
If you left him your phone # to call you, you don’t need to worry, but write or wrong didn’t know that. I hope you’re not upset at write or wrong, she’s just looking out for your safety.
Your friend really knows that you care, and that that’s why you spoke to the principal, but sometimes, as a defense mechanism, people get upset at those who want to help. Hopefully your friend will completely get over it, and appreciate that she has friends who really care.
