Am I The Only One?

Am I the only one who gets to make you laugh, laugh until you cry? Am I the only one who asks you to go, go on without me? Am I the only one who loves when you leave Your hair down in front of your eyes? And who, who do you think I am? And who, who do you think I'll be without you? Am I the only one who had to dress you up to see how you fell down? Am I the only one who needs you to go go on about me? Am I the only one who loves when you leave Your hair down in front of your eyes? And who, who do you think I am? And who, who do you think I'll be without you? And who, who do you think I am? And who, who do you think I'll be without you?
