Answer:
sincerely apologize
point out every mistake you made and take full blame for your actions. if you are sincere they will forgive you. good luck.
ok you should go up to your friend, and ask her what is bothering her (and maybe get her a gift) then if it was you, give her a heartfelt apology. if she is still mad give her time to cool off, but if she is a real friend she will forgive you soon! :)
