He and She, Him and Her

Use he or she as the subject of a sentence. He is hungry.

Use him or her as the object of an action. I gave the ball to her.

The rule is the same when the subject is more than one person:

She and her friend went out. - Correct

Her and her friend went out. - Wrong!

Confused? Try taking out the second person. She went out. She and her friend went out.
