Step-by-step explanation:
A girl...
Just kidding
Write about nature or a place you visited to which you are attached to.
You also write about your favourite game you play cuz thats the only thing you have watched closely in detail.
I know your teacher wont give you marks for this...
You can make up stories like you planted a tree when you were small and you loved that plant alot and you gave water to it...
You also watched the plant closely and if you wanna things better just add that when you grew up you forgot about it and it died......
THATS A GREAT TWIST TO THE PLOT...
HOPE THESE MANY IDEAS HELPED YOU TO COME UP WITH A STORY....
