Sissy has a top secret diary. A diary is essential when you are 10 years old and it’s PRIVATE, of course. Sissy likes to carry her PRIVATE diary all over the house and accidentally leave it open. She loses it at least twice a day. Piper can’t help but peek. She is a little sister after all.
“Stop looking at my diary!” Sissy screams. “It’s PRIVATE!”
“But I can see it,” Piper protests. “You left it right there.”
Sissy snatches her diary up and slams it shut.
“It’s my diary. It’s PRIVATE. You can’t see it!”
“OK,” Piper agrees, “can I smell it?”

That’s a very valid question.
In the Piper’s defense the diary was bought at DC’s Cherry Blossom festival. It may smell really good.
