A man hears a knock on the door…he opens it and looks around but he can’t see any1…he looks down and sees a small snail on the doorstep…without thinking he picks it up and throws it in to the street…
20 years later he hears another knock on the door…he opens it..looks around and sees a snail on the doorstep…he heard a voice saying…‘WOT WAS ALL THAT ABOUT???’
