Who Am I?

Who am I Who am I Am I the same person I was yesterday? Who am I Well the world is changing around me And I can see that I'm changing with it My personality Priorities Are all thrown in the air Or well wait Maybe I'm liquid And I always have to ask myself Am I really here I always have to ask myself well Am I really here? Who am I Who are you Isn't personality a construct We made up so we matter? Is my name what defines me? My name or my body? How can it be my character if it's always changing Everything is always changing And I can't tell if it's just me Can other people see That I'm not the person I used to be Compare to last week And I always have to ask myself Am I really here? I always have to ask myself Am I really here? Who am I?
