When I checked the milk on the counter Tuesday morning, there was really no change except that the cream had separated to the top.
So I stirred the cream in a bit, changed the stickers to the side of the container, and covered it with a cloth.
I must say, I am really surprised that there was no nasty smell coming from the milk when I checked it! There was nothing gross about it at all. It still smelled like milk! Surprise!
