You've just gotten off a long D&D session, and your boyfriend is sitting in bed, watching basketball highlights on his laptop. You snuggle in and tease him a little, because you know that once you get him talking, he won't shut up and you can fall asleep to his voice. And when you suggest that basketball is boring, he indignantly insists that it's actually a lot like D&D. That got him going, so just close your eyes and let him ramble.
