Gokudera's had more than enough attention for one day. The aliens are cool and he could talk to every single one of hem if that weren't so exhausting. And then running into Yamamoto meant he had to put up a front. Honestly, libraries are relaxing, especially if they have books on various worlds... or technology he might find useful.

He's searching through robotics and programming, remote robotics, and then whatever he can find on voice controlled AI. He'd grab that book if he could reach it, and he'd move a ladder to reach it if there weren't a giant metal being in his way.

Coming from a world where the robotic law enforcement had nearly killed countless innocent bystanders, and been used to snuff out any power gain by those in a lesser status, Gokudera is hesitant. He's befriended cyborgs and monsters alike. And... maybe he's staring a little before he clears his throat.

"Ah excuse me. I'm trying to reach one of the books behind you. Could you pass it to me?" Gokudera is wearing his reading glasses, voice soft and rough, and pulling out his best manners. Respect is given, too... he wouldn't dream of getting on the bad side of someone looking as intimidating as Starscream.
