Rule: Indicative sentences end with a period. Interrogative sentences end with a question mark. Exclamations end with an exclamation mark. Following the end mark, leave a space before the next sentence, but do not leave any space between the last word in the sentence and the end mark.
Examples:
Wrong: Has anyone ever come close to playing as well as Jordan
Better: Has anyone ever come close to playing as well as Jordan?
Wrong: She told me, "Don't go into the park at night"
Better: She told me, "Don't go into the park at night."
Wrong: She told me.I didn't want to listen.
Better: She told me. I didn't want to listen.
