The story is about how unthankful Eric is. He received many offers from his friend, but just because he didn't like the stuff he didn't take anything. This lead to hunger for all day long. Sometimes we should be thankful for whatever we are getting, even if we don't like it. At least Eric's friends still thought to help him out. Now after this even Eric's friends would be hesitant to help other poeple who are in need for something. So basically Eric created problems for himself, and probably someone else just because of his likes and dislikes.
Hope it helped!
