One early morning, an old lady was strolling through（漫步） the park when she saw James with a dog.
“Does your dog bite？”she asked.
When the old lady tried to pet(亲抚) the dog, it almost bit her fingers off.
“You said your dog doesn’t bite!”screamed the old lady with blood dripping(滴) from her hand.
“That’s all right. ”answered James,“My dog doesn’t bite, but that’s not my dog. ”
