10 points! Good comeback for mean girl on twitter?

[375]

Ok s theres this girl on twitter who I dont actually know and we used to be really good friends but now shes been acting really mean and bratty towards me and I dont know why! She is being really immature and I find it funny because the things she is saying are really childish and shes 16 and Im 14! I did absolutly nothing to her and shes calling me a b***** and a bunch of other stuff. She claims I "stole" her bio and her username and copys everything I do. I dont and she posted all these tweets about me and she has all these people against me! Idk what to do she still follows me though and the only reason I still follow her is because I want to dm her and ask her why shes doing this. I want to write a good comeback on twitter because Im actually laughing about this because its a stupid fight and I dont even know her. Im trying to ignore her but she wont stop tweeting about me. Should I apoligize? What are some good comebacks? Thanks
