An old man was walking home late one night when he saw a
friend on his knees under a street light, searching for something.
“What are you doing?” he asked his friend.
“I dropped the key to my house.”
“I’ll help you look.” After a few minutes of frustrated
searching, the old man asked, “Where exactly were you when
you dropped this key?”
His friend pointed toward the darkness. “Over there.”
“Then why are you looking for it here?”
“Because this is where the light is.”
