He's about two seconds from abruptly standing up and relocating you to the far end of the cave. He's used to having another presence while he works, sure. But the difference is that the other company he keeps usually understands the concept of personal space.

A few days prior, he'd been busting a weapons smuggling operation when he came across a peculiar bit of tech. He couldn't make heads or tails of it, neither could any of his wards, though with a quick glance, the one takeaway they all seemed to have was "seems pretty alien."

....okay so how'd a Gotham gang end up with an alien curio?

He'd been about ready to conduct his own research when Hal had called him, and asked him not to start yet. Bruce had been ready to ask how Hal had known about it, but Hal had detailed a slew of "telephone" that had started with Dick talking to Wally, Wally to Barry and then Barry to him.

"Just- wait. Please. As a general rule of thumb, alien tech isn't something you want to be poking and prodding if you don't know what you're doing."

Hal had insisted the artifact would be in safer and better hands with the Lantern Corps, but Bruce had declined. It was found on Gotham terf, so it was Gotham's problem. Had been his rationale. Though Hal had insisted against it, the two eventually came to a compromise. The tech would stay in Gotham, but he'd have someone from the Corps sent down just as a precaution. He assumed it would be Hal. He'd been wrong.

Now he's got a Lantern who seemingly doesn't understand personal bubbles, floating behind him, the dull glow of their coloured ring reflected off the Bat-Computer's screen in a way he wasn't a fan of. The push of the ring's mood or emotion also was felt subtly at the recesses of his mind.

He knows you mean well. He knows that every time you reach over and touch the tech or ask him to be careful, you're doing it from a place of earnest care. But he could've already been done cataloguing this thing if you hadn't been there second guessing his every move.
