Im Not Even Sure

Did you think of me when you walked away? Or did you just throw my heart on the floor To watch it die because of me, you couldn't stay? You walked out and didn’t close the door You left it there open for me to see, To see what you left behind You left your past, you left me My head reminds me of what we were like how we loved Everything we were How we fell apart, I’m not even sure Did you think of me when we passed each other Or did you even notice it was me You used to stop Every time you saw me Dead in your tracks Everything reminds me of you Unfortunately You’re in everything I do And it really is killing me
