Lies and Honesty

Why do people tell lies?

Because the truth hurts.
Because the reality is unbearable.
Because the pain is felt when the honest things are said.

Because lies are sweeter to listen to.
Because deceptions are unsuspecting.
Because facades are nothing to be ashamed of.

That's way people just prefer to live in a lie.

But...
We felt nothing if we don't know the truth.
We felt disheartened if the truth is told.
We felt betrayed if we know the truth late.

So what should we tell
to the people we don't want to hurt?
