I've reached an age at which I'd rather pay more for something that "just works" than roll up my sleeves, reach for a spanner, and make it work. Time is money, and the older we get the less of it we've got left.
While I would agree that I write about serious subjects, and that they're not necessarily the most pleasant subjects or even the most pleasant people, as a writer I just think about the humorous aspects of these things - that's what keeps me going when I'm writing a story.
