Hello my name is Jack
you all say "hi" 
nothing here to see
but really that's a lie.
These walls you've seen before
they are quiet tall
subconscious mind of mortar
ensures they'll never fall.
These hands that fidget now
you all have seen too
a smile to fill the silence
but that is nothing new.
These eyes that look away
they have seen betrayal
melancholy and confusion
a friendship not for sale.
This voice you've heard before
it tells you to keep back
although you know it's lonely
it still fears attack.
My story may be strange
to the ignorant view
there may be strength in solitude
but life has room for two.
