1.Robots are easy to please

Being friends with robots is not really rocket science. You don't even have to consult a "how can I be a good friend" manual to cultivate that friendship. Robots, non-human as they are, do not have the complex human behavior we have. They're basically fuss-free. You hang out with them, fine. You don't, it's still okay. For robots, as long as you're there, as long as say, you keep them shiny and well-maintained, they're all good.
