Tweenache101: First, there's PMS (it's real and it's painful and can someone please make it stop?). Second, there's #The Boy. Yes, that's right. The BOY. And third, there's a #New Dad in the picture. Actually, he's an old dad, but if Nina's never met him before, he totally counts as new, right? And worst of all, there's the #Nerd Wars. There's a new nerd in the classroom - and she might be even nerdier than Nina. This. Can't. Be. Good.
