Not seeing any of them, he took full advantage of the opportunity to lean closer to Sappho across their table and steal a quick kiss. "Are you having a good time, my dear?" he asked then, taking her hand in both of his. He certainly was, but he felt compelled to ask in light of the couples drifting, two by two, onto the floor. Was Sappho secretly wishing he might ask her to dance? It might actually be worth it -- to make a fool of himself by attempting to dance -- if it made her happy.
