your parents sound stupid, and that's not something you should say about your parents to a teacher unless you want to have someone come snoop your life and potentially put you in a home. if you're over 16 get a job, or you do make money, so pay your own phone bill. grounding makes me laugh, against, if you're older than 16...
you're teacher shouldn't be proof reading your essay anyways. that's what i don't get. i got my 60% on my own time, and that taught me to work my way up.
