 In this lesson, I'm going to teach you the quick and easy difference between I, my, me, mine, and myself. First, let's look at I and me. I is the subject of the sentence, and me is the object. The subject of the sentence is the person who does the action. For example, I gave John the book. The object of the sentence is the person who receives the action. For example, John gave me the book, or John gave the book to me. This rule is still true with multiple subjects. For example, Dana and I saw Jim at the party. Dana and I is the subject. It would be incorrect to say Dana and me. The teacher called Sarah and me. Sarah and me is the object. It would be incorrect to say Sarah and I. Now let's look at my and mine. This rule is very easy. Use my before the word, and use mine after the word. For example, these are my glasses. These glasses are mine. The word myself is used in two cases. First, as a reflexive pronoun. That's when I is both the subject and the object. For example, I gave myself a haircut. The second case is for emphasis. For example, I baked this cake myself. I'll deliver the letter myself. It means I'll deliver the letter personally. Finally, we have an expression, by myself. This means alone. For example, I went out to dinner by myself. It means I was alone.
