An eyebrow raises at the 'well' golden eyes glancing from her to the computer again - particularly the keyboard this time. He's not aware that she's comparing him to an eight-year-old at the moment, but that's beside the point.

He lifts a gloved hand in indication he's not exactly talking about an inability to grasp the concept of whatever she has in mind. He knew she noticed the automail so there wasn't a point in pretending like it wasn't there anymore. "Might be harder than you think..." Learning how to type with a hand that couldn't detect the location of keys wasn't exactly going to be easy.

It didn't mean he wasn't up for the challenge, but he imagined it wasn't going to go as smoothly and quickly as she seemed to believe it would.
