What really happened to Mary

Mary had a little lamb; its fleece was white as snow.
Everywhere that Mary went, the lamb was sure to go.

Now what if Mary crossed the road, and got hit by a truck?
The lamb would stare at Mary and think, "That was just her luck."

Mary's mother sobbed for Mary all the time after,
But the only thing you would hear from the lamb was its occasional laughter.

Don't think your lamb will keep you safe; you'll really learn quite fast,
That if you rely on the lamb too much, you'll only be part of its past.
