"The two girls - he doubted that either of them was much more than fourteen years old - who had got on in Pinewood were now in the seat in front of him. They were friends, Shadow decided, eavesdroping without meaning to, not sisters. One of them knew almost nothing about sex, but knew a lot about animals, helped out or spent a lot of time at some kind of animal shelter, while the other was not interested in animals, but, armed with a hundred tidbits gleaned from the Internet and from daytime television, thought she knew a great deal about human sexuality. Shadow listened with a horrified and amused fascination to the one who thought she was wise in the ways the world detail the precise mechanics of using Alka-Seltzer tablets to enhance oral sex."
