In college, I took a job cleaning boilers in the university heating plant. The guy who hired me said I needed to wear steel-toed boots so my feet wouldn't get crushed by heavy equipment. He told me I needed to wear long sleeved shirts, even though it was about 110 degrees in the boiler, so if a steam pipe burst, it wouldn't burn my skin as badly. He told me he hoped I wasn't claustrophobic so I wouldn't panic in tight spaces.
I lost a lot of sleep about this job. So on the first day, I showed up early and sat on the front step and waited for my new boss. He arrived and I mumbled something about"I have to leave town." He looked at me intensely for a minute and I was sure he knew I was lying.
Then he smiled and shook his head knowingly and said "It' s about a girl, innit?"
I smiled as roguishly as I could manage and agreed with him. And took the hell off down the street.
