Then it was 'Jill, come here.'
I looked around; it was me she was talking to. I obediently did as told.
'What's fornication? Is it the same as adultery?'
'Um, not really.'
'What is it then?'
'Well, having sex.'
'So that American preacher on Friday night was wrong then.'
'I think so.'
'Is it like when you play with yourself?'
'Um, no, that's um ... (big gulp) (chicken out) something else.'
After that beginning demon possession was no big thing.
P.S. I thought I'd better check that I was right and the American evangelist wrong in his use of the word. According to Chambers fornication is sex between two unmarried people but can sometimes be expanded in its use to involve one married person. So we were both sort of right but I was righter.
