Dear Princess Celestia,
Today I learnt an interesting lesson about friendship.
Sometimes, it's easier to believe you know what's best for yourself and hard to accept help from your friends. But the truth of the matter is, that your friends and family only care about you and want the best for you. You'll most likely find that more often than not, they're not just blowing hot air, and that advice from your friends in any situation, will actually do you the world of good.
Your humble subject,
