Who are we, then?

dear dar(lin') your mom (my friend) left a message on my machine she was franticsaying you were talking crazy that you wanted to do away with yourself

if we were our bodies
if we were our futures
if we were our defenses i'd be joining you
if we were our culture
if we were our leaders
if we were our denials i'd be joining you

if we were our nametags
if we were our rejections
if we were our outcomes i'd be joining you
if we were our indignities
if we were our successes
if we were our emotions i'd be joining you

you and I we're like 4 year olds
we want to know why and how come about everything
we want to reveal ourselves at will and speak our minds
and never talk small and be intuitiveand question mightily
and find god my tortured beacon
we need to find like-minded companions

if we were their condemnations
if we were their projections
if we were our paranoias i'd be joining you
if we were our incomes
if we were our obsession
if we were our afflictions i'd be joining you
we need reflection
we need a really good memory
--excerpted from Joining You by Alanis Morissette

If we are not all these things, who are we? What are we?
