* How could you possibly do that to me!
Place an exclamation point inside quotation marks, parentheses, or brackets, only when it is part of the quoted or parenthetical matter.
* The woman exclaimed, "That car hit the tree!"
* Jenny kept repeating, "I could have died!" throughout the whole questioning.
