Seated at the café

How dare you sit in front of me like that?
Just showing me your back
The sun of your skin, the tattoo in your arm
The impossible arc of your waist

I know nothing about your eyes
But I have memorised your back
Your brown leather shoes, your dark skin-tight pants
Your long hair so black

I wonder how looks your mouth
What colour are your eyes?
Would you give me a smile
if I offer you this rhyme?
