We, human tend to think only we have feelings. But, we have to have recognition that not only we, human but also all living things have emotions.
 

I had an example about that. 
 

I happened to see a television documentary about animals, plants, and mothers of cheetahs living in the wilds of Africa.
 

The children grew up and the day leaving from their mothers has come. The mother's face expression is so hard, and hiss sharply at him. 
 

I have thought the mother is saying to  him to live by himself. That is even like as human do. 
 

It's sure thing that all living things have feelings.
 

Please let me know anything about your thoughts.
