Cows try to deceive by always using the same poker face. The only way to tell if is content or sad is by how they chew the grass... (left to right: content, right to left: sad) [ April 21, 2008: Message edited by: Gabriel Claramunt ]
The death is always on one's left. The cow doesn't know that, of course, but the artist who created the cow does. The cow has that innocent look, reflecting the artist's wish of not knowing. Yet there is sadness there, too, because the cow doesn't have enough power of will to overcome the fear. The best that she could do is to look cute. She'll still end up at the slaughterhouse, but she would take it easier because she carried her mission with certain style.
Cow is not able to understand the concept of inheritance. Thats why she is sad. She had learnt that a class can inherit from only one superclass, but her calf has inherited from her as well as her darling bull. So she is confused !!!
