Having a Grey Moment

It's Winter and I am feeling miserable. I am not happy with the view from my window, i can't see anything which might lift my spirits a little or compel me to write something interesting. The birds in the garden are obscured by fog which I loathe. I find its greyness bleak and negative and all rather pointless? What purpose does fog serve? Pah! I can't find anything nice to say about it......and it's raining rain not cats and dogs which would have been nice.
