A long time ago I read a quotation in a book of advice, which held that the hardest thing about being a writer is convincing your spouse that looking out of the window is part of your job. I have never been able to track down the exact wording or the author of that quotation; when I look online the only source I can find for it is me, because I cite it so regularly. This is perhaps fitting, since my wife thinks I made it up.
It is mid-morning and I am staring out of the window, hard at work. From my office shed I have a clear view of my wife as she struggles to push a wheelbarrow full of soil across the garden. This is a very dangerous position to be in; if I accidentally catch her eye, no unattributed quote about the hardest part of being a writer will be accepted in mitigation.
