My pen is black.
I write with my pen.
My ruler is on the table.
My copybook is on my chair.
My book's title is Harry Potter.
I read a book.
There is a flower on my rubber.
I erase my copybook with my rubber.
My rubber is in my pencilcase.
My pencil is white.
My blue pencil is betwween the copybook and the pencilcase.
Where is your pencil ?
I don't have a rubber.
Give me your pen !
