If something unpleasant has happened, you might have trouble expressing that to your friends. You may not even want to talk about it yet, as the wounds are still fresh. If you embarrassed yourself, or witnessed something strange, use the grimacing emoji. This will tell your friends that something isn’t right, and you might have to call them to tell the whole story. Use this emoji to show you’re not ready to talk, and are stunned by the event. Your friends will be intrigued about what you have to say, but emojis are all you’re willing to use right now.
