I'm Looking At You But I'm Talking To Myself

I'm looking at you but I'm talking to myself Looking straight at you but I'm talking to myself Talking to myself 'Cause I still can remember Words that didn't sound so well planned What is wrong with me? You don't have to pretend to understand Every moment, I am thinking to myself It seems so different, I am thinking to myself Thinking to myself And I don't want to face it Why is everything so past tense? What is wrong with me? This just don't seem to make any sense
