I am reminded of Crash Davis' advice to Nuke LaLoosh in the movie Bull Durham:
Crash Davis:
It's time to work on your interviews.
Ebby Calvin LaLoosh:
My interviews? What do I gotta do?
Crash Davis:
You're gonna have to learn your clichés. You're gonna have to study them, you're gonna have to know them. They're your friends. Write this down: "We gotta play it one day at a time."
Ebby Calvin LaLoosh:
Got to play... it's pretty boring.
Crash Davis:
'Course it's boring, that's the point. Write it down.
Your analog: I can't recall ever acting unethically. I've found throughout my life that honesty is the best policy. That said, I have faced ethical dilemmas. [Provide an example of an ethical dilemma that you faced, show how you considered the perspective of every party involved, and what you did to resolve it empathetically and gracefully].
