No rest for the wicked

Cut the grass in both front and back gardens, as it had grown quite tall during the holiday. Of course I'd rather want to do as little as possible today because I'm still tired. But if I hadn't cut the grass, it would rain tomorrow. (It's always like this.) So, I did it. My next-door neighbour asked me where I had got the energy from just after the holiday. I don't know. Maybe the holiday gave me some extra energy?
