Kicking his foot one last time before he pulled out of his reach, he made a face and looked back over at Remus. When he agreed to his proposition though, his bright smile was back. "I knew you were brilliant, Moony!" he said cheerfully, sitting up before pausing. "Well, if you had to deal with a hangover you could just brew a potion to fix it in class." Sirius said as it it was the most obvious thing in the world. He gave his friend another grin, unscrewing the cap of the bottle and offering it over to him. "Ladies first." he teased.
