She never smiles. Not on Mondays, Wednesdays or Sundays, and certainly not on Saturdays. She never smiles in the morning or afternoon and, beyond any doubt, not at lunchtime. She never smiles to people or to herself. She never smiles. Ever.
Well, almost. She sometimes smiles. She smiles very rarely, just on those odd occasions, hardly ever. You'd probably never see her smile anyway, unless… unless you are in the same room he is. That's undoubtedly not probable to happen… yet, she smiles.
She smiles when he steps in the office, because his grin is so ridiculously contagious. She very much smiles when he winks one eye at her, and she even laughs openly at his jokes because there's no one funnier in the Neitherworld. And then, when he approaches, she blushes. One time she giggled. Yes, she smiles when he's around to call her "babes". Not often, just occasionally, just when he steps in and waves at her. Then she, without a doubt, smiles.
