Everything is scrunched together and the story changes from third person to first person. Please make a new line every time a character is talking so it's easier to read. Put a space after your commas. When a character is talking to someone, they take a break, put a comma before whoever the character is talking to's name. Gah, I'm so bad at explaining and honestly I don't even know what some writing rules are called, yet I used them...lol.
example: "Good morning, class." said Mrs. Brown.
Shes 4 but she's lazy. Very lazy. Like a sloth - This sounds way too choppy. Please, try to combine your sentences together. Take the two sentences, "Very lazy. Like a sloth." and change it to "Very lazy--like a sloth." so it doesn't sound choppy. Also, numbers 1-10 are supposed to be in word form, but it's not a really big mistake.
Also, you don't really need to put a space when someone is talking (I mean after the apostrophes. Excuse my bad explanation.). Just make sure you put a comma whenever the character takes a break when they're talking.
example: "The hat is broken," Steven said, staring at the hat. "I'm going to fix it later."
This is a pretty good story, though.
