Two best friends Emma and Catherine meet each other at a coffee shop and Emma reached quite late.
Emma explained the reason of being late, "I bought a Volkswagen beetle last week and today it broke in the middle of the road. To my surprise, when I checked there is no engine under the hood. The engine lost somewhere in the way."
Catherine said calmly, "Oh really, don't worry at all. I also own a Volkswagen Beetle and have a spare engine in the trunk of my car. You can have it."
