Tegan and Sara may be my favorite group ever. They are great musicians, witty lyricists and they have that amazing ability to get inside your head and make you go, " EXACTLY. That's exactly how I feel/was feeling/did feel." This song is one of my favorites because I think it's so relatable. We've likely all been in relationships where we got so comfortable that we forgot to pay attention to our partner. Over time, you become people living your own lives in close proximity to each other and you have to really try to reinsert yourself into your relationship. I just want back in your head.
