I was so sad (figuratively speaking) when we moved from an older office - but one which had trees all around and even running water - to a very modern, but boring open floor glass paned antfarm-like building.
After some time I got literally depressed. Walking around the concreted block did nothing for me anymore. No trees, no water, no birds, no squirrels. Just cars and a lot of heat in the summer - and a lot of wind during the winter.
