Is there a secret that a person can't tell all his life, even his best friend or relative?

Man evolved from animals! Everyone has a wild side!

Secrets that can't be told are often the most primitive! The human mind is always in a constant struggle between positive and negative sides! Education is to let the positive suppress the negative!

Can't say, because it involves the existing moral norms and emotional taboos!

Some ideas conflict with morality, which will make people feel ashamed!

Some secrets would rather rot in your stomach than tell them, because they will hurt others or yourself!

The human heart is the most complicated! ~

No secrets, no brains!

There are more or less secrets and privacy that can't be said!
