@FumbleFingers What a disturbingly macabre collocation! Historically the only smile that ever split anyone's face was Lizzie Borden's, faces not her own. For whatever reason, I've never read this until here and now; perhaps it’s due to my—ahem, “antemilllennial”—English education in which such grotesque collocations did not (yet?) occur. I recommend more investigation into the more historically typical collocations here via COCA and the BNC. — tchrist ♦ 30 secs ago
