One of my lovely readers suggested I write about motion picture musicals to counteract the general mood of impending doom surrounding the Cat Lady as of late. I forget that not everyone is as immune to serial killers, apocalyptic plague and depressive fits of hysteria as I am, so I do apologize for any darkness I may have unintentionally spread. Let’s just say I was doing it in the spirit of National Suicide Prevention Day, which was yesterday. As in, see, it could be worse – no one you love has the plague, and no one you know has been dined upon by Hannibal Lector. You’re welcome. Sorry if that didn’t…
