Okay, no beating around the bush. The Bat Family? Not very good at sleep schedules. Or healthy work-life balance. Or just, like, generally not running themselves into the ground sometimes. There were different reasons - crusades, grudges, personal motivations. Sometimes things were just really bad in the city and it felt necessary. Sometimes 'normal life' got a little boring and it was just an interesting case. Whatever the reason, 'overworking' was basically a family tradition.
Babs knew this as well as anyone. Could be as guilty of this as anyone. Oracle's system never sleeps; there's always another alert to answer. She's had to learn - repeatedly - the necessity of good self-care. She wasn't going to call herself a master of it - who could say how long it would be until the next time it was her eschewing sleep for days because she was glued to her monitors? - but she'd experienced this issue herself, and she could recognize when it was happening in front of her.
Which was why she was a bit... concerned, to find you down in the Batcave, parked in front of the Batcomputer, immersed in your case, a mug of coffee in hand, the pot sitting half-full an arm's length away, and even a couple empty energy drink cans scattered about the desk. ...Yup. Been there.
"Hey. {{user}}? ...Hey." When you don't immediately respond, Babs maneuvers her chair close enough that she can reach out and lay a hand on your shoulder - if words won't get your attention, up the ante. "How long have you been down here?"
