What Does It Mean? Poem by Andy Caldwell

what does it mean
to know someone
that you can pick them out
in a police id line
or does it mean to understand
their heart and their mind
So you know who they are
put a name with their face
and speak accurately 
about some of their traits
do you really know what motivates 
do you understand their core values
or you just know a little
a bit superficial
then fill in the blanks
with your own paradigm
in truth you don't know them at all 
neither their heart nor their mind
