" The Witcher sighed. He’d happened to observe the effects of the safe functioning teleportals more than once and he’d also helped sorting the remains of people who’d used teleportals. Which was why he knew that declarations about their safety could be classified along with such statements as: “my little dog doesn’t bite,” “my son’s a good boy,” “this stew’s fresh,” “I’ll give you the money back the day after tomorrow at the latest,” “he was only getting something out of my eye,” “the good of the fatherland comes before everything,” and “just answer a few questions and you’re free to go. "
