Something I Have Done

A man was walking down the street when, around the corner, he discovered a girl begging on the ground for alms. The little one was dirty, looked hungry and kept shivering. She was holding on to an old blanket to warm up.

That man, seeing the scene, exclaimed:

"Sir, how do you allow these things?" Why don't you do nothing to help that girl?

As he turned the corner, he heard a voice:

"Of course I've done something: I've done you."
