How do I deal with this?

tell these people "has it ever occurred to you that the reason i am treated differently just may be because i treat her a little differently than you? i dont know maybe.. or maybe because i do my home work and u dont. Maybe she doesnt check my homework coz i do it all the time, unlike you. quit talking bout this teacher and how she treats others better, coz its your choice if you want her to treat you nicely or not!"
