Vision

I read a text in Chinese. "两只狼来到草原，一只狼很失落，因为他看不见肉，这是视力；另一只狼很兴奋，因为他知道有草就会有羊，这是视野。"

I like this little text. Here is it in English. "Two wolves came to the grasslands. One wolf became depressed, because he could not see the meat, this is his sight; the other wolf became very excited, because he knew there would come sheep as there was grass, this is his vision."
