Sirius thinks it's a Joke
Sirius walked into the common room and sat by the fire. Remus put away the letter he was writing to Orlando Bloom.
"Hi Sirius," Remus said.
"Hey Remus! Say, that was a funny little joke you played on my yesterday!" Sirius laughed, slapping his knee.
Remus groaned. "Sirius, that wasn't a joke."
"Ha! There you go again!" Sirius said, clapping Remus on the shoulder.
Remus angrily tore out of the common room, leaving the Orlando Bloom letter. Sirius picked it up.
"I think you're very hot and you have the nicest ass I've ever seen. You have chiseled abs and stunning features…" Sirius read aloud. "OMG Remus loves me!"
