One of those backward steps

Our flatmate David just told me that my mother called last night. On finding out that we weren't home, Mum decided to talk to David instead. She asked about his Christmas. Then she said, 'So, what do you think about Michelle and Heather?'

Pause.

'I think they're beautiful, wonderful people, and whatever they want to do is fine with me,' he replied.

'That's a good way of putting it,' Mum replied.

David, of course, was not impressed. He said, 'It's like ... What do you think of Heather and Michelle BEING LESBIANS AND ALL?'

Some questions are not questions at all, just monologues that end with a rising inflection.
