There is a picture lingering in my brain which I want to see again, but cannot find the source.
In that picture, all mane six were present, and they were paired;
Applejack with Rarity
Fluttershy with Rainbow Dash
Pinkie Pie with Twilight Sparkle
For each pairing, there was two sentences for each, which displayed how opposite the pair was.
I can't remember the exact words, but I think it was something like this;
"Be graceful" "Be rough" for Rarity and Applejack,
"Be quiet" "Be Loud" for Fluttershy and Rainbow Dash,
"Be funny" "Be study" for Pinkie Pie and Twilight Sparkle.
If somepony can find the source of this image and tell me, I'll be very grateful.
