Yes, I've been a pega-sister since the first FiM episode, now I catch myself saying "Everypony" & "Bucking" or something like that. I've also become more fashionable (Thanks to rarity), I'm smarter and more athletic.Although there has been some negative side effects, I'm shy, I tend to throw myself into books more than human contact (Which isn't as bad as it sounds when you think about it).
