Answer:
This question requires a personal answer, since the poem has to be made by you. I will give you a short poem as an example, that you can take and modify it as you wish.
Explanation:
Today I saw the snow
It was like being on a show
The white floor under my feets
The cold wind on my cheeks
I spent the whole day outside
Just to see the the beautiful sights
And at night I came back home
Just to dream about what I saw
