The Posturing Birds

Birds can be nasty, often failing to keep their opinions to themselves. This Tall Bird is critical of the
girl's posture: "Stand up straight, or you'll get stuck like that." A passerby defends her, "Hey buddy, your posture isn't so great yourself." Meanwhile, a ghost chimes in "He's just trying to help!" To which the other ghost replies, "Stop it. You're just posturing."
