Exactly. There was nothing even happening, yet Remus felt like he was ecstatic and Sirius' mood was only fueling his even more. He felt brilliant and thought the same of his friend and he wasn't even sure how they got there. Well, he knew it was the bike, but it wasn't the physical part he was questioning.
"Fantastic. It'll happen, definitely." Moony grinned at Sirius, trying to think of what he'd dress in if he were in a band. Leather, he didn't think, he would go too well on him. Unless he kept his hair really untidy and grew out the lines that appeared on his jaw every day. Actually, yes, he could see it, stroking his chin with his fingers.
Without thinking, he even grabbed Sirius' wrist, tugging his arm completely around his own shoulders but he didn't let go. Partially, he was lost in his thoughts, but he also just liked the feeling.
