Twitchy Eye/Playing With

Twitchy Eye: A character's eyelid spasms when emotionally unstable.

Straight: After she fired from her job, Alice's eye twitches whenever it is brought up.
Exaggerated: Alice is Ax Crazy, and this is her basic expression.
Justified: Alice has Tourette's Syndrome.
Inverted: Alice's eye twitches when she's trying to avoid laughing (of the genuinely humorous kind).
Subverted: Alice's eye twitches normally-no one's really noticed that until she was fired, and she keeps the twitch after she gets her job back.
Double Subverted: The reason nobody noticed it was that it only gets that bad under stress.
Parodied: Alice's eye twitches on every opportunity, except when she's unstable.
Zig Zagged: ???
Averted: Alice's eye doesn't twitch.
Enforced: The writer's can't stand emotionally unstable people, so he mocks them by placing this character in one of his shows.

Invoked: ???
Exploited: ???
Defied: ???
Discussed: ???
Conversed: "Um, is her eye like that normally?" "No, it isn't. Keep your distance, and try not to being up sensitive topics."
