Basically write a steam of thoughts on fall OR winter, whichever you like more C:
My thoughts on winter...
I think of the way frost looks on bare trees, my cat hopping through the snow, the smell of eggnog and cinnamon, the way the lights look on our fake green tree, how the rush of heat feels on my pink nose after coming in from the cold, holding hands with my dearest in the snow, and how when i think of these things the best memories come back.

* Write a steam of thoughts however you'd like about fall or winter!
