9. If memory is what holds the Big Plan together, then forget it.

Planning her new strategy, Mimi remembered the big problem with each of her past strategies - her memory. Devising her strategies is fun and creative, but they always fail because she forgets to check the results.

After a long day of school, teachers complaining and friends being mental, who can remember to see if a trap has been sprung?

What to do, what to do...

Hmmm, she thought, maybe an actual trap? A bear trap or something like that? Maybe Susy would chew her own leg off to escape. That'd be cool! Then Mum couldn't deny it, and while they were at the hospital, Susy would have to admit what she'd been up to. So where does one get a bear trap?

Sigh, but seriously. How to catch Susy in the act and prove once and for all what a horrible little sister she is. Proof that Mom and Dad couldn't ignore or gloss over or say oh but she's just little.
