PublicAdventures/Patty-6-FindOlderSister1

You think you might be able to offer some diplomacy with your older sister Emily. She often times takes a lion's share of the breakfast leaving you with very little, and you've just about had enough of that business. Still in your jammies, you leave your room and head to Emily's. There's a black sign on the door. Two skull and crossbones with ominous "DO NOT ENTER" wording in deep red.

Knock first.
Barge in without knocking.
Decide against bothering Emily and go get breakfast.
