Sibling Rivalry

From the introduction: • We're getting a dog! Who's going to take care of it? Who will it sleep with? • Dad went on a business trip. Again. Mom is unhappy. • One of the siblings broke their leg and has to miss out on something. What is it? Does the other sibling get to do it anyway? • Grandma is dying. She's really mean, but everyone is crying anyway. • There is a party coming up that everyone is going to be at. Why haven't we been invited?
