Sister is on the left. Brother is on the right.
Sister: What's wrong, Brother?
Brother: You know what's wrong, Sister.
Sister: No, really, I don't. What's bothering you?
Brother: Just leave me alone and let me sulk in silence.
Sister: Geez. Come on. Just tell me.
Brother: The sweater I'm wearing . . . It's yours.
Brother: I said it's yours.
Sister: What are you talking about?
Brother: You're wearing my sweater. The boy sweater. Blue, green, yellow. Get it?
Sister: I think this sweater looks lovely on me. The colors are beautiful.
Brother: But the one I'm wearing has the purple and . . . gag . . . pink in it. It's supposed to be for you.
Sister: Oh. Right. But still - I look great! You need to be more secure in your baby boyhood.
Brother: Bite me.
