She's tired. Time for bed.

She looks at you for a minute, a funny expression on her face. Then, with a quick, cute shake of her head, she dismisses whatever image she had in her mind and turns and heads for the stairs.

"I'm really tired, you nut. Come on. Let's go to bed."

You follow her up. You each get ready for bed in silence, brushing your teeth, using the toilet, going through your usual routines. As you get in bed, you wonder what she had been thinking before coming up the stairs. When she kisses you good night, her gaze lingers on you for a moment, that same odd look in her face. And then, with a quick "I love you," she turns over and turns out the light.

You lay in bed for a long time, frustrated, but planning to rejoin the discussion the next day. The weekend was starting, so maybe a little morning sex would be possible.

You finally fall asleep, but your rest is troubled by odd dreams.
