I'm sick of being nice to this two faced girl?

I have almost the same problem, thsi girl uses me to get rides to school cuz her own dad wont drive her and like her stepmom cares. and shes so mean to me when we get to school and ive told her not to comeany more and she still does! BUT BACK TO YOUR PROBLEM, tell a teacher, ignoring her would be the best idea. ignore her play back if she says something agree and be liek Yeah totally and than just turn your back, if that doesnt work talk to a counceller/teacher
