Omg this made me so mad i know the exact feeling. Experienced that in my high school like 4 years ago.. That girl was rude but you clearly have your head on your shoulders.. You should feel empowered thst you didnt stoop to her level and act they way she did. It probably brings you bad feelings thinking about it now but one day you'll look back and it will feel completely different. Hopefully she realizes how rude she was and apologizes if not thats one mean girl.
