Went to Edinburgh recently, very nice. Saw an outward view of the castle and visited the camera obscura, princess street and witnessed the Christmas Market.

I find it mysterious how I look at fish at the aquarium and how I cannot determine if they look happy or not. Are we human because we can smile, laugh, enjoy and be happy?
