Smiley face with a waving hand
On the surface: Goodbye with a smiley face.
Below the surface: “I despise you and really don’t want to talk with you. Please go away.”
Background: Thanks to the smiley face, this is not a simple goodbye, but rather a mocking expression used to respond negatively to whatever one objects to.
Guidance: If you see this emoji, you might want to change the topic, or just keep your mouth shut. If you wish to retaliate sarcastically, consider sending back two waving hands. Or just deploy just a hand for a genius goodbye.
