Then Leighan sends me a messages saying "you lier taylor can't go camping shes in hilo and p.s dont even be lyk the boy who cried wolf." then she blocked me that didn't make any sense at all . And then before that she always, was physically rude, racist, and insulting. Any time I sat down by my bff kirah she would push me away and sit there. thats not right and anytime i sat down near her or any of my other friends she pushed me away. She calls me halley caus we live in hawaii and im from washington im skinny and average height blond hair and blue eyes. She tells me o im not gonna be ur friend if u go any blonder or get those blond highlights kirah wants u 2 get because blonds are snobbby rude sy girls. And then all the time shes calling me anorexic which im not im absoultely sure of im 12 and i way 73 pounds and i eat more then most kids my age i just have high motabolism unlike leighan. and shes allways calling me stupid caus im blond and rich.
