A Good Deed Gives Award

I have been roaming the city streets for a long time now, I really do not have a destination, suddenly, a man stands on my way and politely greets me.

He asked for direction to the public prosecutor's office which I showed him.

After which I continued roaming, all of a sudden, a nice-looking old lady advanced to my side and gave me fruit, before I could munch it, the man to whom I had shown direction came and snatched the apple. I thought that he was a benevolent man but to my astonishment, he wasn't!

After this thought popped, a few seconds later. The old man gives a dog the apple which made the dog lose his life forever.
