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.

- Fullmetal Alchemist:
- Roy Mustang lies to the Elric brothers about where Hughes is, saying he retired so they wouldn't blame themselves for his murder at the hands of Envy. This doesn't last long, as Maria accidentally spills the truth about his death to them later that day.
- 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.

- Harry once he figures out Hermione's heritage, and almost everyone else who knows/figures it out, though mainly at Wanda's behest (because she wants a clean break/to keep Hermione as far away from the burdens of being related to her as possible). When Hermione figures it out, the excrement hits the fan. Especially because while Harry regrets keeping secrets, he isn't exactly apologetic, either...
- There's also the small matter of keeping Bucky's heritage from Ron, which is potentially a much bigger problem.

- In Saw, when Lawrence throws Adam his wallet to show him a family photo of him with his wife and daughter, Adam opens it up onto to see that it's been replaced with a picture Jigsaw put in there of the two of them, bound and gagged, assumedly for Lawrence to find and spur him into killing Adam to save them.

- In Mr. Holmes, Masada Umezaki's Anglophile father claimed that Daddy Had a Good Reason for Abandoning You and used a meeting with Holmes as an excuse. 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. Later, after Umezaki's mother dies and some realizations on Holmes' part, Holmes sends a letter claiming that he does remember Mr. Umezaki and that he did sterling service as a British agent. It's a fiction, but one that will help Umezaki.
- Given a different twist in the original novel, A Slight Trick of the Mind. Again, Holmes has no memory of meeting Mr. Umezaki. However, he also realizes that he must have done so and that he has burned the volume of Watson's diaries that contains the record of this encounter, probably because that volume included politically sensitive information.
