Just to inject a little humour, I will tell you a short story.
When my wife went to college, her parents bought her a beater car for commuting.
One friday afternoon she arrived home & told her father, her car was making a funny noise.
After a quick preliminary diagnosis, her father told her, he suspected that she had lost a piston!
To this my wife replied, " well, if I can borrow your car, I could re-trace my route and possibly find it again ".
P.S. She still doesn't know anything about cars today.
