My first ChatGPT prompt
Write an ode of love in the style of Shakespeare
to Nina. Make sure it includes references to her
home town (Tlemcen), where we met (Dubai)
and our new home (London). Make it happy and
cheery, yet romantic. Sent by Dobo who was
born in Bourgas, Bulgaria and travelled the
world to find Nina.
DR
Oh fair Nina, from the land of Tlemcen
My heart doth beat for thee, like a drum
In the bustling city of Dubai we met
And from that moment on, my heart was set
Your beauty and grace, like a shining star
Enraptured my soul, from near and afar
Now in London we reside, a city of dreams
Together we thrive, in love it seems
My heart is yours, forever it shall be
Nina, my love, you complete me
-Dobo
