Walking outside, Tim soon realized why he felt as he did, and why his friends were acting so strange.

His car was missing! A light bulb went off in his head when he realized his friends had pulled a birthday trick on him. He was not angry or unduly surprised.

“Yes, but only one of us took it. Can you figure out who it was?” asked David.
