If I want a dose of good cheer, all I have to do, in fact, is glance across the living room to my windowsill where this little fellow hangs out. My sister bought him for me some time ago and thanks to his photovoltaic cell he oscillates from side to side in an ever-so-slightly mocking dance (‘the effect is far more mocking from the back’, points out Ms Formerly Aldgate). Once the sun is out and striking in his direction, there is no stopping him, no matter what you do. I have been trying and failing to locate the cartoon he reminds me of – a pair of grinning Victorian mutes in top hats and mourning coats declaring ‘O nothing can downcast us’. I know I’ve seen it somewhere.
