maria called in sick today , and i do n't want to throw you into bed with grendel unless you were first in bed with maria - because of the contrast thing , you know , the shocking contrast between being with a beautiful sweet girl one moment and then suddenly realizing you 're lying in bed with a nasty old witch the next moment - being taken unawares like that - getting the full dose of that frightful shock of horror one gets when one suddenly realizes one is no longer next to the lovely maria , but next to the monster , laying right next in pitch darkness to a really nasty hag .
