Ron came up beside her desk and leaned against it, careful not to displace any of her papers. Any other time he might have teased her about staying late, or her organisation or any other number of things related to her job, but he just didn't have the energy.

Chinese take-out, maybe a game of chess?"
He hesitated a moment before adding, "Been awhile since we've done that, yeah?"
