Seems to me, right is always prudent.
But then again, there is the question of "Do these pants make my butt look big?"
Now I'm conflicted.
Let me try to help you with your “conflict.”
The correct answer to whether a pair of pants makes a butt look big is “no.”
The butt is either big or not big on its own merits.
Hence, you can be both honest and prudent with a one-word response.
