Pinkie!

Twilight : *using her magic to flip a page of her book* "you know... pinkie is getting a bit too repetitive with her party thing. and her confetti surpises are a bit annoying." *she sighs* rainbow dash: *she groans* "i know! its getting a bit... not fun?" *she tilts her head* Fluttershy : "o-oh.. but i think shes fun!" *she says softly looking down* Rarity : *she stops measuring the cloth* "i agree with twilight darling." Applejack : "shes our friend.. but i agree."
