How do you know which pronoun to use in a sentence?

Explanation:

Pronouns have three cases: nominative (I, you, he, she, it, they), possessive (my, your, his, her, their), and objective (me, him, her, him, us, them). Use the nominative case when the pronoun is the subject of your sentence, and remember the rule of manners: always put the other person's name first!
