The concept of Time Travel.
Were the portal to open in the sky
the heavens to split and
the past to rain down upon
the present world,
Would you jump in?
Would you fly through the
silver tube of past time
bump shoulders with your 12
year old self
kiss forgotten love once more
in the shadow of imminent  
Expiration because it has not yet
reached it's expiring date.
Are you living with no regrets?
Or an insane plea to change
Everything.
