It is obviously a good ploy to get the lawn mower out just when you hear a guest's car wending it's way along the lane! Having artfully placed comfy chairs in good view of where you plan to mow you can swing into action just as they settle down with a good book. A nice, sunny day is definitely best as you are bound to look genuinely hot and bothered. What kind hearted soul can sit there with his feet up when you puff and pant to and fro with your woefully inadequate lawnmower?
Once you have lured your guest out of his seat you can then go and hide in a secluded spot and soak up that summer sun!
