I'm going to call my spanish teacher rude and obnoxious
Why do you want to insult your teacher?
It's easy to hurt her because she's a softy.
It's unacceptable to treat your Spanish teacher like that. You're supposed to respect your teachers and be polite to them, not call them bad names.
I might get a bad grade but I don't care.
You should care. What reason do you have to hurt your teachers feelings? You should be polite to your teachers.
