I can do it on the train in the morning, in the afternoon on my days off of work, or late at night when the DH and the dog are sleeping. Sometimes I do it on a TV tray, while I'm watching television, but not often, because it's harder to concentrate that way.
I'm talking about writing, in case you're wondering.
What about you? When does inspiration strike you?
Are you a morning person, or does it take you a while to wake up and get started?
Or maybe you're a Night Owl?
Please tell us. When do you do it?
