why are you all I think about

there’s so much to see and too far to go 
I thought I knew everyone I used to know
words left unsaid but nothing worth saying
i don’t know why you’re in my head lately
why were you the one who caught my eye
after everything, I wish I was blind
you know where I live, have my number
but you won’t talk to me, it’s such a bummer
I was always in your head until you kicked me out
why are you all I think about
