This is yet another song written by Andrew on the hardships of having a serious relationship while constantly being on the road. He describes his time alone with his girlfriend as a relief from the commotions of touring, "singing to only you" and being away from the crowd. He makes the time he spends with her sound brief, saying "soon I'll be leaving you." *Sniff Sniff.*

I think "As You Sleep" is another song Andrew wrote because he's so in love with his girlfriend and he wants to be alone with her so badly. When he says "Don't you wake up yet, cuz soon I'll be leaving you, soon I'll be leaving you, but you won't be leaving me," it is about him having to leave on tour again; maybe he's leaving her while she's asleep to go on tour again and he loves her and doesn't want her to wake up yet.
