In my experience robots aren't any fun to hang out with because they try too hard to please humans and they don't get any of my jokes, but robot friendship experiences may vary.
It's cool if you want to hang out with a robot, I definitely won't judge, but watch out for robots who drink beer- because the booze has fried their circuits, so they may go a little haywire. Such shocking behavior! (Comic via Poorly Drawn Lines)
