The Helpful Old Lady
One afternoon, an old lady, laden with shopping, noticed two small boys on the front step of a house. With their bags and uniforms they were obviously going home after school. They were on tip-toe trying to reach the door-bell with a stick.
"Poor little lads, they can't get in," she thought, "Parents these days just don't seem to care."
So she marched up the path, reached over the boys and gave the bell a long firm push.
The surprised boys turned around and screamed "Quick, run!" and promptly disappeared over the garden wall.
