I can remember studying the faces in the floral carpet of my bedroom floor as a child. They were rather like friends keeping me company.
I suppose this also explains those who see Jesus in toast slices, or clouds.
I'd also assume we can all find faces if we make a point of looking for them.
Mamya, re your friendly polar bear; Andy Capp kept me company, as I slept at nights, from being a 12 year old schoolboy until I became a 16.5 year old soldier. A water mark on the ceiling (which kept coming back no matter how many times dad painted it) was the image of the head and shoulders of the cartoon character - complete with fag in mouth :-)
