Go outside, they said. It will be good for you, they said. Well, how can they know if it is good for us? Sure, it is brighter and greener outside, especially when the sun is shining, plus breathing some fresh air could lift the spirits a bit. But going out means preparation, a change of clothes, putting on a pair of shoes, opening the door, then closing it behind us and locking it, sometimes it even entails going down at least one flight of stairs. That can be tiresome.
