I think I'm going to make this into a series.
Dear Lily,
Prongs: Oh sweet Lily! The apple of my eye! The…!
Padfoot: Mr. Padfoot would like to inform Mr. Prongs to kindly shut the hell up because Mr. Padfoot does not need to hear Mr. Prongs gushing.
Prongs: Mr. Prongs would like to inform Mr. Padfoot that Mr. Prongs has had to listen to Mr. Padfoot gush over Mr. Moony for the last two weeks.
Moony: Ferme-la avant que je te viole avec ma cane!
Padfoot: Mr. Padfoot would like to inform Mr. Moony that Mr. Padfoot and Mr. Prongs do not speak French so whatever Mr. Moony just threatened is completely lost to Mr. Padfoot and Mr. Prongs.
Moony: Mr. Moony would like to inform Mr. Padfoot and Mr. Prongs that Mr. Moony just threatened to rape them with a cane if they do not shut up.
Padfoot: Mr. Padfoot would like to inform Mr. Moony that he is incredibly hot when he speaks French.
Moony: Padfoot, don't, we're writing a letter to Lily…mmm.
Padfoot: Mmm. Mr. Padfoot would also like to inform Mr. Moony that he tastes good.
Prongs: Mr. Prongs would like to inform both Mr. Padfoot and Mr. Moony that he is still in the room and does not need to see Mr. Padfoot and Mr. Moony snogging.
Padfoot: Mr. Padfoot would like to inform Mr. Prongs to bugger off.
Moony: God, Sirius…
Prongs: MR. PRONGS DOES NOT NEED TO SEE MR. PADFOOT'S HAND IN MR.MOONY'S PANTS!
Moony: Ah!
Prongs: LA LA LA!!!
Moony: OOH!
Prongs: LEAVING!
Padfoot: Good.
Moony: AH! SIRIUS!
Prongs: Is it safe to come back in?
Moony: Sirius you bastard! Come back here with that letter!
Padfoot: What letter?
Prongs: Looks like you have a pissed off werewolf on your tail Pads.
Padfoot: FLY OWL! FLY TO LILY EVANS!
Lily finished reading the letter and laughed. "They are such idiots sometimes," she smiled and tucked the letter back into it's envelope.
"Shut up before I rape you with my cane"(ferme-la avant que je te viole avec ma cane).
Yep, it's going to be a series.
