Saila is visiting with her daughter and I am uncomfortable and not especially happy to have her there.  Her daughter and Bibi are getting along quite well.  Otherwise, nobody is relaxing around the visit.  Rob is especially annoyed that she's here at all.  I am trying to make everyone as comfortable as I can but when we sit down together to have some coffee and such, Saila begins singing a hymn.  I can sense Erin and Rob both becoming tense, even angry.  "Saila," I say, "I think you have to leave now."  She frowns.  "You are making everyone uncomfortable and I don't think you care.  You are a guest in my home but you are no longer welcome."  She starts spouting off about the wrath of God dropping fire and brimstone on our heads.  Bibi looks around confused and I become more firm. "Leave now. You are not welcome here."  She gets up to leave and I head to the door to close it behind her.
