I am a very nervous flyer.
During a trip from California to Indiana, it didn't help that my connecting flight from Denver was delayed twice because of mechanical problems.
Then, after we were aloft, I noticed the lights began flickering.
I mentioned this to a flight attendant.
"I'll take care of it," she said. Moments later the lights went out. Clearly she had solved the problem by turning off all the lights.
A passenger across the aisle who had been watching me leaned over and said,
"Whatever you do, please don't ask about the engines."
