My brother bugs me all the time about my Diary.1
He wants to know what sisters write in total secrecy.2

I tell him that my Diary is boring as a textbook,3
but only so he doesn’t try to take a sneaky look.4

The truth is that my Diary’s like a novel from the store5
where I’m the leading lady whom the characters adore.6

It’s amazing, how this parchment documents each thing I do:7
my nightmares, observations, and my love for peach shampoo.8

I explain all my misfortunes in a sister’s constitution,9
where I outline all my problems and devise my own solutions.10

What’s unexpected are my words on sibling rivalry;11
in spite of how I act, my brother means the world to me.12

That’s one fact that stays under lock and combination;13
How embarrassed I would be, if he knew my admiration.14


The truth is that my Diary’s like a novel from the store5
where I’m the leading lady whom the characters adore.6

It’s amazing, how this parchment documents each thing I do:7
my nightmares, observations, and my love for peach shampoo.8
