Aye - it is, as Ian said, a 3D day over here too.
I think I can understand why people suffer from SAD - we seem to have had weeks of low cloud, mist, dark grey skies and rain varying between heavy drizzle and heavy downpours.
Never mind the size of my gas heating bill - I reckon the electric bill will be up as well thanks to the number of times we've had lights on in the house all day
