This is excellent, but if you would like an example, picture this,
You have a friend. You are comfortable and at a level conveniently above neutral. This friend has some radical tendencies and beliefs. They start ranting about the imbecility of our generation and how stupid people can be and so on and so forth, but it's all really just white noise, only blacker. Suddenly, they slip on their words and, conveniently, a banana peel, and fall down a flight of stairs. You laugh a bit, but with complex undertones, because you're a complex person. Ironically, they've injured their tongue, and cannot speak for several days. To add to the emotional damage, they've fractured their jaw and need to wear a face brace for the next several days. Snarky is your facial expression.
