Already

Twenty minutes, of unbareable silence.
I thought you would know I had a lot on my mind.
Three days, hardly any words exchanged.
I thought you knew what I've been thinking.
But I know you. The less you speak, the less you care.
And I know by the tone of your voice
you'd rather be somewhere else.
And when exactly did you change
your mind to change your heart?
And when exactly were you going to tell me?
Because you're sitting right here,
but I already miss you.
