Secrecy is an idea which presumes
men can't read minds to each other.

I don't buy 'regret' idea.
I need life's good lesson.

Don't live in regret! It is such a useless idea.
Use the memory to prevent us do bad things!
Regret is a childish wish, or an empty hope,
trying to revise the bitter memory of the past.

If your heart tends to force friends to do as you say, seed of discord is being planted in your relationship.

Privacy seems not an illusion for those
who want to believe in secrecy principle.

Conscience is a kind of stored procedure which was planted in mankind's collective unconscious. Someone has the buttons to control it.
