Thoughts About Happy Ending of Stories

I used to like stories with a happy ending, especially love stories;and I guess many people, especially kids and yong people like stories with a happy ending.

About two years ago I watched a movie called Training Day with my friends. When it was over, I thought to myself,'Is there any such happy ending in real life? Yes, there is, but sometimes(maybe often) in real life bad guys like the corrupt cop in the movie would win and take the money and those who were bullied would be in frustrated and disappointing.

I had the same thought after I watched the movie again this winter break. But I was still glad with the ending, which was encouraging.

After I read the novel 'The Lord of Flies', I felt relaxed when I read that a captain appeared so that the boy who was being chased could be safe. But later I thought to myself, 'What if the Capitain didn't appear?'
After I read Wuthering Heights(a great novel), I felt comfortable with the happy ending. But after a while I thought to myself, 'what if it had an unhappy ending?'

I am not pessimistic. Actually I was encouraged and I felt comfortable when I finished the movie and the stories above. The movie and the novels with the happy endings(and they are good endings), to some extent,encourage people and let people see the lights of hope.

I asked myself 'what if...' just because I thought there were many possibilities in life and you never know whether you would have a happy ending with your own story.
