Oh yes. I had a 'friend' in high school, an only child. We'd be doing some group activity and look around and "Hey! Where did Kirk go?"
Next day, I'd ask. "My TV show was starting". No goodbye, no excuses, just said it like it was a reasonable thing.
See, he valued 'friends' as long as they were more entertaining than a TV show. Then he'd simply choose a more entertaining option. Screw the friends; screw social norms; just go stimulate his senses with something else for a while. Totally self-interested in a sense.

So only children can certainly be strange.
