Guilty Pleasure

I have no clue what group this belongs in... Maybe none, but sometimes I turn off all my lights in my room around 9pm so my stepmom can stop nagging at me. I get so happy when I do this. At a certain time of the day, I just want her to hush and leave me alone so I can fold clothes or lay down or read a book. I already talked to her about this, she doesn't care, so I have no choice but to act like I am sleeping.. Do you guys have guilty pleasures?
