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
