If there are two objects in a sentence, the normal word order is: person - thing
Ex: She told me a story.
If the thing is a pronoun, it stands behind the verb.
Ex: I must give it to her.
If we want to emphasize the person, we put the person after the thing.
Ex: Let's write the letter to John in California.
Using the words describe, explain, report, say - we always put the person after the thing.
Ex: explain this rule to you.
