Wait until dark. Give yourself a good scrub beforehand. Everything you think you don’t need to wash, wash it twice. Everything you think you need to wash, wash it four times. With a selection of different soaps. Just to be sure. Put on clean clothes. New, if possible. If possible, new and unworn, but washed once. But make sure they’re dry. Go somewhere high up. Ideally pick a day when the sky is clear, but don’t wait too long. A little spritz of perfume wouldn’t be unappreciated. Just make sure it’s not too musky. Something fruity and floral. Like that Britney Spears one. What was it? Cosmic Radiance. Yes, they’ll like that.
