Si ou pa tap fikse le ciel ou pa ta we letan kouve? ..what does this mean?

Si w pa t’ap fikse lesyèl ou pa t’ap wè tan an pare – If you weren’t staring at the sky you wouldn’t have noticed the weather is grey (or something like that)

It’s a cheeky answer to the question “why are you staring at me?”  (Poukisa w’ap gade m konsa?)

It means,  if you weren’t staring at me you wouldn’t have noticed me staring at you.
