My DS "got in trouble" (not BIG but little trouble) with a teacher earlier this year because some classmates were at an exterior door, wanting to come in, and DS wouldn't open the door. He said he didn't recognize them so he didn't open the door, as they've been instructed.

He swore up and down he didn't recognize them. His teacher found this a dubious claim, because those classmates have been seated near him all year.

DS says he "doesn't pay attention to things like that." I wondered, then, if this was a real thing, or if he was just being a pain.
