Well, i could ass well as any other just say "Fluttershy, she's the best pony" but i don't think fluttershy is the right one in this case, im a lot like fluttershy myself, and i think well just sit in akward silence and look at each other
Pinkie Pie is too hyper and happy all the time, i think i would get tiret of being with her
Twiligt might be, but again, she's a lot into books, and i don't know if we would have anything to talk about
I simply can't see myself with Applejack or Rarity, donno why, they just don't fit me
so i think if i should pick a GF it would be Rainbow Dash, im sure every single moment would be interesting and fun
