I'm dating a stright a student who is like the perfect daughter. Her parents don't know about me.. I hope... I want to take her to the movies for our 1st month since we started going out... her parents are mean.. and I don't want to get her in trouble... what do I do?

First there is no such thing as the perfect person hun... If the parents don't even know of you yet don't you think it would be a big shock?. why has not their daughter told them about you yet?
You might have to fore-go the first month movie don't either of you sneak around because us parents are pretty smart you know lol
Why don't the two of you start having book studies at her house (keep it as a study) so her parents can get use to you.. can't just rush in like a bull in a china shop saying here I am nice to meet you, it's our one month anniversary can she go to a movie?
Then in time they most gradually will accept you seeing the daughter outside of studying
Let them get to know the person you are and don't try to fake what your not cause they will see through that
