Everyone's got a favorite episode (Mine's Cutie Mark Chronicles), a favorite character (Mine's Rainbow Dash), or a favorite song (Mine is "Love is in Bloom").
What I haven't found out is: What's your favorite Friendship Lesson?
I have two personal favorites:
The first is from "The Mysterious Mare Do Well" (Ironically my least favorite episode): Don't act like a sore loser if someone else outdoes you in what you do best; be happy for them.
The second is from "Dragon Quest": What you are is not the same as who you are.
So, out of every report given throughout the show so far, what's YOUR favorite Friendship Lesson?
