Dear Gilda,
You are a mind-cringingly loudmouthed hate-chicken! Just because you're pissed off that Pinkie stole your girlfriend doesn't mean you lost the ability to not scream every other word that you spew from your bile-coated beak, you obnoxious pussycock, and I hope you cried when you realized Rainbow Dash wasn't offering you makeup sex.
Yours sincerely, Discord.
