Talk:Derpy/@comment-25559529-20150530233800

I think I know what happened with Derpy and the invitations in Slice of Life. Ever since her cameo in Feeling Pinkie Keen, fans have made her out to be the mail pony, right? And we know that she is rather ditzy, so maybe she ended up delivering the invitations a day early, which just so happened to be the day of the monster attack.
