Greetings)
Interesting thoughts, so many different things...and sometimes contradictory...

To keep silent and hide the truth from a person because it might hurt them? Or because you will be treated unfriendly?
But if you don't tell him the truth now, his pain will be worse tomorrow. So will your regret that you kept silent or lied.
But the truth, the 100% truth, will set him free. Freedom is always achieved through pain. Remember Jesus. He was not silent, but always spoke the truth, which hurt many, and created hostility toward Him. But He knew that no half-truth or half-lie would ever save anyone.

That's why there are so many problems in our society, so we try to be silent when we see someone else's problems, being tolerant and respecting their freedom of choice. And we don't call things by their proper names.
Like, for example, those same alcoholics and drug addicts. Where does the whole process of recovery from addiction begin? With admitting 100% of the truth - "I am an alcoholic" or "I am an addict. And with a public confession, so that neither you nor others have any way of hiding the truth.

Clearly, there are different moments in life; this is just one aspect of the great and multifaceted subject of truth.

Thank you for your reflections, I love how you capture subtle matters from various sources and turn them into such interesting and profound topics, and I'm glad that you(and @iskafan) and I are bees of the same hive))
