I think in different ways. If I'm writing a short story, or anything creative, I sort of see a picture or 2. If I'm working hard on, say, proofreading a job app. for my daughter then I'm very clear-cut, logical and a 'straight-liner'. Mostly I think like a skein of wool that a kitten's been at and OH looks at me in bafflement. He thinks in straight lines. I can almost guarantee that if there is a small task to be done I'll do it the obvious way and he'll do it the obvious way.... they are never the same way and baffled glares ensue. The past is a huge, rippling pool interlinked as one unit and developing and moving into shallows, up rivulets etc.. Is that what you were asking about?
