No sir, absolutely not, sorry, but no.
Not sorry, actually-just no.
Keep it simple, plain vanilla: nope.
Not happening. Big en, big oh.
No way, no how.
Negative, nuh-uh, ixnay, nyet.
No no, no no.
No-no-no-no-no-no-no.
Not likely, not likely. Maybe,
but I doubt it.
Possibly, conceivably, in theory.
Uh-huh, mm-hmm . . .
Well, yeah, sure, O.K., why not,
oh definitely, yes,
wow, I mean anything,
anything at all, when can we begin?
