Oops turns out my mom doesn't like the thought of me listening to rap music

I mean it's not like I'm not 17 and able to see rated-R movies without a parent's permission or anything. It's not like I'm constantly cussing around her, smoking weed, drinking, or being a bad kid in general or anything. It's not like I'm going to be off to college in about 9 months or anything. It's not like I'm gonna keep listening to it anyways or anything. I'm glad she didn't walk in during Yeezus though.
