OK

She made a visor with her hands and looked up at him.

"So 4/8, what does that sound like?"

He doubled-timed a beat for her.  Da da da four da da da four.

"I guess that's why they don't just call it 1/2, then, huh?"

He stared at her. 

"You know, reducing fractions."

He laughed.  Of course she would think that way.  He touched her lightly.  "Yeah, so then I guess 4/4 would just be...1."

"Ok, so what would that sound like."

Da.

She laughed harder.

"Wow, I'm amazed you never made it as a rockstar.  That was really, really good.  Can I have your autograph?"

"Smartass."

She pulled a pen out of her purse and looked around.  "Here," she said, handing him the sleeve from her coffee cup, "sign this."

He turned from her and started signing.  Behind him the sun was setting and a crowd was forming, waiting for a tour to start.  He turned back toward her, proud of himself.  "Here."

She looked down at it.  May I kiss you now?
