Welcome to everything you need to know about robots.
First of all, they love you. There is a lot of science fiction written about dangerous killer robots. This stuff is all baloney. Robots were made by aliens to make the world a happy place. They tickle anacondas, they teach pumas how to wrastle, and they do their best to put smiles on human faces. So next time you're getting off the bus and walking down a dark, rainy street towards the corner potato chip store, if you happen upon a giant robot don't freak out. It's probably just trying to help you stay dry.
Remember, robots can dematerialize and shlorp through a building, so if you startle them don't worry about it.
