I have three teenagers and also remember being a teen like it was yesterday, and the best thing i can say is to be honest with your parents. Sometimes when my daughter is trying to tell me something, i get all caught up in the emotion of what i think my daughter is trying to say. When that happens, she calmly says to me "mom, i'm trying to tell you something. Can you just listen to me please" and that usually works
Honesty and respect are two tools to use with parents that will usually work to your advantage.
Good luck!
