From my POV, as it has evolved since D-Day, tough question. It's all in The Knowing, isn't it?

I mean, if I know something about you -- something that affects you, affects our partnership (business, romantic, Sunday morning softball league, whatever) -- am I under a moral obligation to share it? At first blush one might say, "No; Golden Rule; if you don't have anything nice to say, etc."

But -- if I take action(s) based on The Knowing Of It, what then is my moral obligation?

Is withholding information the same as hiding information?

Is delicacy the same as deception?
