You were the one who said it's over Now you wanna come back So take your hand off my shoulder This time it's not like that Cause I know where your heart's at I know you like to be alone But hate being lonely When you see me doing well That's when you call me Now I'm doing fine Don't need you in my life I guess you're missing me now Just because you're lonely Doesn't mean we go back to the start Just because you're lonely Don't mean that you can't play with my heart Who do you think you are? Just because you're lonely Doesn't mean we go back to the start Just because you're lonely Don't mean that you can't play with my heart Who do you think you are? Who do you think you are? Who do you think you are? You say you've changed and you're different But I don't wanna hear that Your friends are saying that you miss me But I already know that Cause I know where your heart's at I know you like to be alone But hate being lonely When you see me doing well That's when you call me Now I'm doing fine Don't need you in my life I guess you're missing me now Just because you're lonely Doesn't mean we go back to the start Just because you're lonely Don't mean that you can't play with my heart Who do you think you are? Who do you think you are? Who do you think you are? Who do you think you are? Just because you're lonely Doesn't mean we go back to the start Just because you're lonely Don't mean that you can't play with my heart Who do you think you are? Who do you think you are? Who do you think you are? Who do you think you are?
