Cheryl comes in the house practically in tears.
Cheryl: The check engine light came on and it’s sputtering. I was afraid I wasn’t going to get home. I’m taking your car to finish errands.
Me: I’ll drive your car in a bit and see what’s going on. She leaves, I finish what I was doing and then go to check her car out.
I start the car. It sounds fine. No Check engine light. I proceed to drive it around for about five miles. It drives fine.
I return home to find Cheryl in front of the TV.
Me: Honey, whatever it was doing, it isn’t doing it now.
Cheryl: I’m not crazy.
Me: I don’t think you are; however, it’s not doing it now, so there’s nothing for me to diagnose.
Cheryl: It really didn’t do anything? The check engine light isn’t on?
Me: It drove fine. Do you want to go out with me and see for yourself?
Cheryl: (Exasperated sighing) No. It won’t do it again until I’m alone, because it clearly likes you better!
