I have to write a narritive in class

Dear Readers,

In my class we are writing a narrative about time travelling. We have to pretend we are time travellers. At the beggining I said I was travelling in my Mercedes Benz time machine and we have to pretend we are telling the story to your friends. You have to write in first person. I am done my good copy and my teacher is going to be marking them over the Christmas holidays.
