A man saw a boy standing beside a dog on the road. He was passing, from a far distance he asked the boy if his dog bit, the boy replied, my dog does not bit.
Then the man continued his journey towards the boy, getting closer to the dog he stretched his hands towards the dog and the dog tore his shirt and bite him, then he asked the boy but you said that your dog does not bit.
The boy answered, "yes but this is not my dog".
