Use your manners

Setting: It's Sunday morning, Max and Mom are already up and moving around downstairs. Max likes his alone time with Mom or Dad in the morning. Unfortunately for Max, Emma wakes up shortly after they get downstairs. Mom and Max at the bottom of the stairs looking upon a descending Emma:
Max: "Mom, Emma needs to go back to sleep!"
Mom: "Max, she's your sister. Be kind. Show your good manners."
Max: "Emma, please go back to sleep."
