COMPETITION FOR POEMS, IN WHICH THE FIRST LINE MUST BE ROMANTIC, BUT THE SECOND LINE SHOULD BE THE OPPOSITE.
This was the winning entry sent by Joao Caitan :
My darling, my lover, my beautiful wife,
Marrying you messed up my life .
I see your face when I am dreaming ,
That's why I always wake up screaming .
Kind, intelligent, loving and hot ;
This describes everything you are not .
I love your smile, your face and your eyes ,
Damn, I'm good at telling lies !
My feelings for you, no words can tell ,
Except for maybe 'Go to hell .'
What inspired this amazing rhyme ?
A bottle of Feni, little Salt n Lime !```
