Remus hates it when Sirius writes things on his shoes. He hates it because he is hopeless at cleaning, domestic spells and really prefers to do such things by hand anyway. And he would ask someone else to do the spell, but the boys are all hopeless and he's afraid to show the girls some of the things Sirius write on his shoes. There was one time when Sirius had managed to write a narrative about sodomizing Severus Snape with a banana on his penny loafers and his mother had actually contacted Mrs. Black to tell her about it. It had been a very unpleasant summer for both of them.
So, when Remus walked in and saw Sirius hunched over a pair of shoes, tongue stuck out comically and brow furrowed in concentration, Remus threw a pillow at him.
"Hey!" Sirius cried as he toppled off the bed dramatically, flailing in a manner of unnecessary ways. "What was that for?"
"Don't write on my shoes!" Remus said in the sort of desperate voice he usually reserved for his roommates' treatment of books. "I like my shoes. They're the only shoes I have. And I don't like having vulgar things about Professor McGonagall written on my shoes!"
Sirius shook his head and sighed nostalgically. "That was a good one. You didn't even realize it until you got to Transfiguration, and oh the lovely colors she turned."
"Not lovely," Remus corrected. "Frightening. Very frightening colors. Sirius, I don't like detention. Or being yelled at. I don't consider it the highlight of my day like some people."
"You should," Sirius advised him. "Could loosen you up a bit."
Remus just twitched.
Sirius rolled his eyes and got up off the floor. "Anyway, quit with the pulsating vein, grandma. They're not you're shoes. Message is for you though." He tossed one of his sneakers at Remus, grinning madly.
Remus just stared at the top of the shoe, unsure of what to say. It was very heavy in his hand. It was an odd sensation given how light his head was feeling. He didn't know quite what to say or if he should say anything or if this was a joke or if Sirius was actually being... Well, he wouldn't go there.
Sirius waited a moment and then grinned widely. "Glad you feel that way." He gave Remus a quick peck on the cheek before grabbing his hand and pulling him out the door. "C'mon. It's dinner."
"Umm..."
"I'll nick some chocolate for later," Sirius added, winking lecherously.
"Okay," Remus responded, his voice very high.
It was a very, very long dinner.
