What punctuation mark comes after a person yells?

The punctuation mark that comes after a person yells depends on the context and the tone you're trying to convey. Here are a few options:

* Exclamation point (!): This is the most common punctuation mark used after a yell. It emphasizes the loudness and intensity of the yell. For example: "Get out of here!"

* Question mark (?): This can be used if the yell is also a question, like "What are you doing?!"

* Comma (,): This can be used if the yell is followed by a direct quote or further explanation, creating a pause. For example: "Stop that, now!" he yelled.

* Period (.): This can be used if the yell is simply a statement and doesn't need emphasis. For example: "Go away."

Ultimately, the best punctuation mark to use will depend on the specific situation and the desired effect.
