No. Let me explain.
It begins with the letter, ‘N’, and while you reckoned a three letter response, yours has only two. Not one of them is a ‘Y’, ‘E’, or ‘S’, as you may have fancied, so I strongly advise you reassess things.
It is, you’ll find, the exact opposite of your expectations. You were likely anticipating a wide smile, corners furling in affirmation; but, instead, you were met with tight lips. Do not misinterpret this as a playful “kissy-face”; inasmuch, you may sense derisive undertones… and you would be quite astute.
Further, do not presume any change. Ever. When earth reverses polarity, when North becomes South, concrete direction may prove ambiguous; however, rest assured, my answer will not.
No means no.
