It's funny, a little bit, because of the drama of 'you monster' that is usually only used to ironic effect.
And yet... it would be funnier if my mother hadn't died of cancer, I think. Maybe then I wouldn't be up writing about it at 1.45am to try and get it out of my head. It would be funny if it weren't something I worry about so much.
