water

I have mixed them all.
I have dropped ice cubes into boiling hot: they sizzled and sighed and they lived and died.
I have rushed cold into hot and calmed hot into cold so that I could reason it out with lukewarm.
Now it is getting cold, the eternity of ice is longing to turn me numb.
In the end it will be all about mist for me but they will see icy remains.
