I just realized I work with a second person who smiles improperly.  Not like bad teeth or anything, but both people generally smile slightly when they talk.  This is fine in normal situations, but they do it pretty much all the time.  Not all situations call for smiling, which is why I've been having such a hard time reading them.  My instinct is to smile with them (either because I'm a sociopath who copies facial expressions or because that's what apes do), but I find myself questioning why I'm smiling when there's clearly nothing to smile about.  I feel awkward, but it's actually them who are awkward. #sociology
