How do i write an essay on something kind i did for some one 500 words

Here's how you do it:

-- Sit down, turn off your cellphone, mp3 player, gameboy, radio, and TV.
Look out the window at the trees, and let your mind wander.

-- Try to remember something kind that you did for someone.  Surely
you'll be able to think of something.  If not, then the first thing you
must do immediately is run out and do something kind for someone.
Otherwise, you'll never be able to complete this English assignment.

-- Once you have the event in mind, take a pencil and paper, think about
the event, and just scribble down a few words here and there as you
remember things about it.  What did the person need ?  How did you
know about it ?  What made you decide to do something ?  How did you
decide what to do ?  What did you do ?  How did the other person feel
when you did it ?  How did you feel when you did it ?  Stuff like that.

-- Now, take the notes you scribbled down, and tell the story, from
the beginning to the end.  While you're telling the story, write down
what you hear yourself saying.

-- When you have the whole story written down, you'll have a lot more
than 500 words, so you'll have to tighten it up and cut it down.  Don't
take anything out of the story.  Just tell about the same things with
fewer words.  That'll make it a lot more interesting to read too.

-- Finally, just before you hand it in, read through it carefully, or ask
your mom or big brother to read through it, and find any mistakes in
spelling or grammar.  Correct those and hand it in.  I can promise that
you'll be happy with your grade on it, and even more important than that,
you'll learn stuff and your writing will get better ... that's the whole reason
the teacher wants you to do this.
