That's so sad and rude. Please don't let it affect you. I f I were you I would wear it daily in front of her and put it somewhere she could see it not in my locker and I would be so happy with it!! It actually is her problem not yours. Even if she does not like it (which I doubt, it is an amazing bag) she will at least see that she can't put you down. I am just trying to say that you are on top of this situation not her, so act accordingly. She is just miserable and this is how she acts too.
