Your post on using "pase pou" leads me to ask how to say "I'd rather not." in response to a request to do something.

pase pou → rather than,  instead of (conjunction)

For sentences such as:
I'd rather not, I would prefer not to  
We use H. Creole verb PITO (to prefer)

I'd rather not.
I'd rather not go.
M ta pito pa ale.
You'd have to repeat the verb ("ale" for instance) after "pa".  We could not just say "M ta pito pa" in Creole.

I'd rather not.
I'd rather not stay too long.
M ta pito pa rete twò lontan.
