The fact it was red made Felix question whether it was from one of his Gryffindor friends, since he wasn't expecting to recieve one romantically. As he read the note, his heart dropped for a moment, a flicker showing across his face. He knew he couldn't please everyone, that not everyone in the school would like him. Then he considered that someone had spent one of their finite number of roses on him. Sure, it was to tell him he sucked, but they'd left it anonymous so what did they expect Felix to do with this nugget of information? If the person who had sent him this had a genuine gripe toward him, they should have told him, otherwise all this rose told the third year was that he was worth a fifth of their attention. If anything, they'd just given him an ego boost and with no problem to fix, why should he worry about the negative connotations? "Thanks," he grinned to the Slytherin, pulling the note off the stem. "But you know what? I tend to kill my roses pretty fast, got no where to keep them," he explained, handing it back to the prefect. "You take it, as a thank you for delivering. Happy Valentines Tempest.
