Snow has some unique characteristics beyond being cold. Just a thin layer of it can completely disguise any garbage dump, barren field, or a mass grave. With that remarkable ability comes — maybe paradoxically, maybe poetically — the ability to be stained by almost anything.
It’s interesting that that which can blanket any blemish, also shows the smallest drop of blood, oil, or piss.
Snow bears a lot of symbolic meaning in various languages and texts. Some refer to it as the purest form of white. I think it’s interesting that something so subtle and delicate and so easily stained can cover any pre-existing blemish. It can make anything look pure and it can do it without saying a word.
You might wake up and find that that it came in the night and everything is covered in fresh snow. And you’ll see that it can make even the most degregated parts of town look clean and new.
