Well, actually, the dog doesn't so much tell me this as he yells it. Usually while he's chasing me. Often the dog gets so angry when he sees me that he tries to catch me. I don't know why he gets angry. I guess some dogs are just highly excitable that way. But when he runs after me, he can only go so far. Then his leash stops him.
I try to point things out to the dog, purely for educational purposes. I live in the school yard, so I am a very well-educated squirrel. I say, "Man's best friend, huh? You're tied to a tree. You did notice that, didn't you? My friends don't tie me to trees."
Time and again the dog gets so angry about the life lesson I've tried to give that he forgets about his leash. He lunges, he runs out of leash, he bounces back.
Very calmly, not to tease him but only to explain the way things are, I say to the dog, "I think it's squirrels who are man's best friend. That's why the man who lives here ties you up--so you can't bother me."
The dog is not very smart. He does not appreciate my trying to educate him. Sometimes the dog gets so angry he forgets words. He barks the bark that is just noise: "Bark! Bark! Bark!"
I never forget words, and I never bark.
Still, the man who is not the dog's best friend is not very smart either. He doesn't realize that he doesn't have to tie up the dog to keep him from catching me. I can always climb a tree to get out of the dog's reach.
From the tree, I can drop walnuts onto the dog's head.
Purely for educational purposes, of course.
