Seeing The Lens

The teenager lost a contact lens while playing basketball in his
driveway. After a fruitless search, he told his mother the lens was no
where to be found.

Undaunted, she went outside and in a few minutes returned with the lens
in her hand.

"How did you manage to find it, Mom?" the teenager asked.

"We weren't looking for the same thing," she replied. "You were looking
for a small piece of plastic. I was looking for $250."
