Obey Pamphlet
You plan on obeying the Pamphlet, you really do. But the appropriate time to tell your Sisters just never really comes up. At each meal for the next several days, you resolve to make this the time, because you know you have so little time left. And at each meal, you let the time pass by without grabbing hold of a moment and making your announcement. And while you could ask permission to use the Case you found in the Hall Closet, you are sure it is probably fine to just use it, so why bother Ci about it?
