Maybe she just didn't think she smiled naturally? Understands what it looks like, but has no idea how to imitate one when asked.Plus eyes do tend to get bigger when one smiles, but not enough that I'd call it a notable feature.Or something to explain away Henry's tendency to have super-wide eyes.I don't know, like I said I may just not be grasping it right because I haven't seen this smile myself.Does she recognize a smile when she see's it on someone else though?Because honestly, this sounds more like a case where she just thinks that she specifically isn't capable, but understands what a smile is.And because she thinks she isn't, she tries very hard to overcompensate for it.

I would assume that she can recognize a smile on someone else, though I don't understand how, seeing as how she doesn't understand a smile as I describe it to her.

Like, she was surprised to hear that you're supposed to show your teeth. She said she thought that "showing your teeth is a sign of aggression". And I was like, "Well, yes, it is... among chimps, and probably some other ape species, but not among humans, generally."

She then said that the reason she thought that showing your teeth implied aggression was because, in her hometown, she used to hang out with "vampire people" who would hiss and "bare their fangs" at people. She then demonstrated what this looked like. I then told her that while teeth are involved in that gesture, [i]it still looks nothing like a smile.[/i]
