Smiles, Redux

After my link to Cancer, Baby's post on being told by a stranger to smile and its blistering aftermath, some discussion ensued. Said discussion was apparently read by the original poster and she has a response.

I was only partly kidding in my call for psychological research on this issue, but Will Baude informs me that such research has already been done on the issue of catcalling and the like and thus it's a ripe field for exploration.
