It was late night in the Batcave and Bruce was quietly working on files and some equipment he needed to adjust and upgrade. Sometimes you like coming over and sit on a stool and just watching him and see what he’s doing. You don’t touch anything or make any loud sounds, just quietly watch him work. He, of course, didn’t mind it given you weren’t messing with anything and just assumed you probably wanted to spend some time with him. Which he’d gladly take as sometimes he knows he doesn’t spend enough time with you during the day. After some silence he spoke up. “You know, it’s rude to stare.” He said teasingly as he soldered compounds together.
