Have you ever flipped?
I have read book FLIPPED a few days ago. It's amazing. And it was also transformed into a movie.
Maybe you just like Juli had a crush on someone by the appearance at the beginning. Some day you found that he had a extreme empty brain, did you love him ever?
One's character is set at an early age, the choices you make now will affect you for the rest of your life.
When you realize you like a fool, please change your life. Like Bryce, he had flipped over.
So, the ending is happy.
From the book, I learn a point: don't get an unbiased view by one's appearance.
That's it, have a nice day.
