at first i thought about the lyrics literally, but now i'm wondering if tegan is refering to the mind of the person and where their thoughts are instead of their body physically. the whole "when i find myself outside your house, i'm trying hard to figure where you went" could be interpreted metaphorically as finding herself outside someone's thoughts. and the "where do you go when you're not here with me" could be her asking where their thoughts are if they're not with her. or maybe that's just me
