Poison ivy came up like a rose 
 in red and thorny garb
I look, liked and did dare touch
my pals my avid touch espied
 with green and frosty eyes
I should've only looked, and not leapt,
 For away and over my rising moon she flew
On clipped wings of my dream
  Now a song-filled air pocket of serenades
A love's wretch, my dream is a hornbill
 Flightless and tottering.
 My dream remains a dream still
Now my dream is a locked-up serenade
