Cat and Dolphins playing together

In an age when it seems that everyone is fighting, from Arabs in the Middle East, to politicians in Ivory Coast, it's refreshing to see that some creatures can ignore their differences and show curiosity rather than enmity!

In fact, why is it that humans are so aggressive and so destructive? Aren't we supposed to be the clever ones? The ones that can find cures for major diseases? The ones that can build skyscrapers and put men on the moon?

Perhaps it's us that can learn from simple animals about the value of play and trusting in another creature irrespective of that fact that it's different from us.
