That sucks. And that is why you should save every now and then. Let this be a lesson. It's happened to me several times. It sucks.

Ctrl+Z works if she only deleted the text. if she trashed the file, it should be on the recycle bin / trash folder, whatever your computer calls it. Otherwise, unless it was really short, a file recovery program may be faster than retyping it. Just make sure the program's legit.

Aren't her bite marks smaller?

Well... she has issues. And so do your parents.

Did you check your computer's recycling bin ?

Your own fault that she was able the access things. Your laptop should have been password protected and not left logged in when unattended. You getting in trouble is one thing, but the loss of the essay is entirely on you. Sleep mode should require password on resume, and you should use sleep mode or log out any time you're leaving the laptop unattended gor a period of time that isn't long enough to merit a full shut down. This is just common sense. Now the whole biting and blaming you thing is little demon child youngest child behavior and your parents should know better, especially if they had younger siblings.

You should get her back

Wait doesnt it save automatically word for word. It does on my laptop

Wait until midnight, then pee in her bed.

What a ******* bitch, hope she got exposed about the ordeal.
