Although Nadia smiled, it wasn't an expression with any true joy.  She really did look exhausted.  "I, um, I don't sleep well," she explained, a clear understatement.  "I get nightmares."  It wasn't something she really wanted to talk about.<br/><br/>All the survival movies make everything seem so easy.  So many people die and you move on, as if everything is fine.  Logically, it seems so simple, so obvious.  The movies she'd seen never got into how difficult it could be, just going from day to day to day, knowing how many other people died who had actual useful skills and how it should have been her.<br/><br/>"I don't really want to go down right now."  She pulled Lizzy over so that they could sit down together under a tree.  "I just...I don't know.  I don't want to have to think for a while.  I don't want to have to deal with all this right now."
