Why does my teacher hate me?

So im a jr in hs and im taking a 2 year spanish class, even though i already speak spanish. This is because even though i can speak it, i hear alot o peopl say that puerto rican spanish is really ghetto and not proper so i wanted to learn it properly,also cause i coupdnt bare the thought of takinf french... But i swear my spanish teacher hates me! I dont ever do anything wrong either, i sit quitely in class, do all my class work and homework and get good marks on my test and quizes. Alot of other kids in my class draw pics of her on the board and yell and talk out of term but she dosent care she is still nice to them. She gives me this weird look all the time like she dosnt want me there, then she never calls on me in class even though participation is part of our class grade. The other i had a question about some work and raised my hand, she literally looked at me and thenwalked right past me. Idk why she hates me but it feels like she just does its annoying and i dont feel like i deserve it. Dose she have a right to treat me like this?
