David stood guard by the entrance, like he was told. He watched as his old professor walked out in a beautiful red dress. He couldn't help but think how they would have looked good if A: He was aloud to wear his 'gryffindor' robes, and B: if they had been together. Neither of those things were true, so David thought it stupid to even consider it. He did however, wish to have a chat with her, so when she sat down not to far away, he called out "Professor? I am not allowed to leave my post, but if you wish for some company, I am happy to provide." He smiled slightly. She always got him, when these Aurors didn't at all.
