"My spirit of Hearthwarming sense is going off! That means a song is coming on!"

"Dear Princess Celestia: It's great to have fun, but it's even greater to have great friends. And having lots of friends means that you sometimes have to make choices as to who you'll spend your time with. But that's okay, because good friends will always give you lots of opportunities to have fun. So even if you're missing out, it's never for long. Respectfully yours, Pinkie Pie."
