Still, it seemed to us that the main reason we were hated must be that we always lived by stealing. From the earliest times, rats lived around the edges of human cities and farms, stowed away on men's ships, gnawed holes in their floors and stole their food. Sometimes we were accused of biting human children; I didn't believe that, nor did any of us⎼unless it was some kind of a subnormal rat, bred in the worst of city slums. And that, of course, can happen to people, too.
