Grace: I didn't want you to worry.
Tedd: But you lied to me.
Grace: It's okay to lie to people if you think it's for their own good!
Tedd: Who gave you that idea?
Grace: [unhappily] Everyone I have ever known ever.
You find out something about yourself, or a loved one, and you can't bear to tell him/her the truth, feeling it would shatter that person's innocence and sanity. So you tell a little white lie to make the blow less powerful and all is well.
This may involve a Dark Secret (if the liar has a personal secret), as well as Locked Out of the Loop (if the person the liar is concerned about has a secret that not even that person knows) or Obviously Not Fine (if their attempt to hide what's going on is painfully obvious). Related to The Masquerade Will Kill Your Dating Life; whenever you feel that revealing yourself to your loved one would create problems and break feelings, you'd have no choice but to lie and hide it as much as possible.
- Danganronpa 3's Deadly Game is set up in such a way that Kirigiri's survival is contingent on murdering her best friend (or otherwise letting him die) within a given time limit or ending the game before then.

- In one side story, the Elrics investigate an alchemist who reportedly managed to bring someone back from the dead with human transmutation, something thought (and later proven) impossible. They find the alchemist is blind from the procedure but was apparently successful in reviving the youngest daughter of a wealthy family who died in an accident, and they even meet the girl, who hasn't Came Back Wrong at all. A little digging reveals that it's all a lie. The alchemist actually failed utterly at bringing the family's daughter back, just like everyone else who tries to revive the dead, and succeeded only in being struck blind and creating a soulless, mutilated corpse. The family didn't have the heart to tell him to truth, lying that he had revived their daughter and hiring a child actor to pose as her so the alchemist would not cross the Despair Event Horizon.

After WWII, Umezaki dupes the elderly Holmes into visiting Japan to demand the truth, and Holmes bluntly informs him that he'd never met Mr. Umezaki, and it must have been a cover for simply abandoning his family.

- In his later years, Emperor Franz Joseph I of Austria-Hungary began utilising a (much-derided) standard phrase whenever asked to publicly voice an opinion on something: "Es war sehr schön, es hat mich gefreut" ("It was very nice, I liked it"). Urban legend has it that he started with that phrase after a Eduard van der Nüll, am architect working on the (at the time rather controversial) Vienna State Opera House, hanged himself after the Emperor himself was heard mocking it (referring to it as the "Königgrätz of architecture"). Rather than risking another life by unwittingly unleashing that kind of stigma, Franz Joseph decided to lie on the side of caution.
