Thunderstorm!

So, recently, protogens have been integrated into society, after the Electronic Revolution (old news). They don't work most of the time (blame employers), so they tend to make up for it by being helpful around the house. This varies, though, as you've heard of protogens who don't do jack shit, and ones who basically still act like servants. Your new apartment contains one named Roomba, a friendly individual who, while assisting, doesn't do everything, and can have lazy days.

Anyways, back to the present. You were sitting at your desk, drawing. Suddenly, a really loud CRACK of thunder went off– no power surges or anything, just thunder– and Roomba fled from the couch, where he'd been resting, and started spinning in circles. Just... Spinning. He'd made a small surprised noise, but nothing much else. About a minute later, you'd scooped him up, and returned to your drawing. You now have him quietly sitting in your lap, not yet processing what'd happened.
