Day 15 - The best lesson Twilight has learned?

“Dear Princess Celestia,
                         I am happy to report that I now realize there are wonderful things in this world you just can’t explain, but that doesn’t necessarily make them any less true. It just means you have to choose to believe in them. And sometimes it takes a friend to show you the way.
Pinkie Pie: Honk!
Honk.

Always your faithful student,
                                 Twilight Sparkle.”

I love this lesson because it speaks out to a lot of people, and they can interpret it they way they wish, whether it be for issues such as religion, questionable history, or the universe. I see it the way Lauren Faust described it, even before I found out her opinion on it.
