The dogs next door get a little noisy, so one day somebody called animal control to complain. When the officers arrived, I heard my neighbors tell them, “Hey, dogs bark. It’s human nature.”
–Kent Kollmer in the December 2007 Reader’s Digest, page 190
In fact, this is substantially true. One of the principal reasons people have dogs is so that the dogs can do things to other people that the people cannot do themselves: scream at visitors so they will go away; drop their droppings on the lawns of people they do not like, etc.
