[She can hear him come in the front door, closing it quietly behind him with a click. It doesn't take long for it to become abundantly clear that it's him rather than John Watson because there's the clink of him moving around some glass beakers to check on an experiment--something John wouldn't touch--then the fridge opens and closes, and there's a yell of:]
John! We're out of milk!
[--as if it's purely John's job to shop. (Oh, he does sometimes but John still handles the bulk of it.)]
[Then there's silence as Sherlock looks around when John doesn't answer back, and the huff of annoyance when he finds the note saying John's out on a date tonight with *~Angelica~* (what kind of name is Angelica, anyway?) and that hopefully he won't be home until tomorrow and that Sherlock is fending for himself for dinner.]
[That's alright because it's late enough that Sherlock's already eaten something. He stole some of Lestrade's donuts right off his desk when he wasn't looking earlier.]
[Since he's planning on settling in for the night, he goes into the bathroom and the sink starts to run, and there's the sound of him brushing his teeth. He putters around while brushing his teeth, leaving the sink running (a habit that drives John crazy because it wastes water, but who cares when John's out with *~Angelica~*) so he's still brushing his teeth as he walks into his room to hunt for the pair of pyjamas he wants to wear.]
[When he sees Irene sitting on his bed, he stops, completely frozen in place, the toothbrush still in his mouth.]
Lol yup
John! We're out of milk!
