Where should I separate this paragraph?

I know this paragraph is too long and I was wondering where to separate it:

In spite of her anger, Collette was spurred to send a secret note right back to Bessie. Collette quietly ripped a piece of paper out of her notebook and scribbled down a message she would not want her mother to see. The waded piece of paper flew through the air before landing squarely on Bessie閳ユ獨 desk. She and Natalie read the note quietly. Afterwards, Collette could feel both of their eyes burning through her golden blond hair and right into her brain.

Thanks.

(What did you think about the writing, by the way?)

It's fine as it is--definitely not too long, so it doesn't need to be divided. The only thing that needs to be corrected is that "waded" should be "wadded." "Waded" means "walked in water."

You don't need to seperate this paragraph. And it's not too long either. I like it.

The paragraph is very well written but is too sharp and to-the-point for you to make a split. I suggest you make it more descriptive, and take another look at it.

Are you kidding? Leave the paragraph the way it is. Its not too long its only 5 sentences. It expresses a complete thought without rambling on and on and on. Splitting it up would ruin the readers' train of thought.

By the way the closing sentence is excellent. GREAT JOB! But you really need to leave it the way it is.

Standard paragraphs should be between four and five sentences long ... you're just fine with this as it is.
