This picture could only be more perfect, in my opinion, if there were earphones dangling from her ears and maybe the stereo next to her didn't have the Spongebob theme. Oh, and if she didn't have a smile on her face.
If you must have a teenager of your own, I highly recommend getting one of the mildly autistic variety. Sure, the preschool years were hell, but she's never once told me she hates me, demanded a brand-name anything, or refused to go to school with that zit on her chin because what if someone sees her? How many moms of teens can say that?
