a 18 year old girl i don't like

There is  this 18 year  old girl i don't like because  she thinks she is better then anyone  and   i get  to annoyed  and to figute and i don't like  people  staring   at me   cause i  always  think that people think of me  in the  wrong way. I don't  like the way  she  talks/ laughs   that just  annoys me   and   she  knows how to stab  people in the back and  pretend  thats she is  your  friend  ,  and i don't  anything about this girl  cause she   talks  low  and   don't speck up right  and  sometimes around the holiday's she don't dress up  right   and don't know how to do things the right way.
