I took this picture yesterday which was a very grey day. However, it has been an even worse day today with heavy rain and wind so I've cheated and uploaded one from yesterday.
The evergreens add colour to a winter scene (as others have already mentioned) - what is one supposed to do if you take 2 good pics on one day, & then the next day it pours & you feel low! Don't worry, we all do it at times.
