Nope - in fact for me Sunday is the only day that I really relax and think 'there's absolutely nothing that I have to do today'. We don't even cook lunch if we don't feel like it, we'll just have something light and simple. In general all the chores are planned for the rest of the week, and so long as I've completed some of what I planned it's all good.
This morning we went for coffee and sat and did the crossword - just warm enough to sit outside and people watch. I arranged some flowers (sounds good but actually it was only some chrysanths from Waitrose ? ), cooked lunch, ate it and now we're sitting down with our feet up watching something about dinosaurs while I skim through GN. Nothing exciting but all things I wouldn't really do the rest of the week.
