My first job, at about age 16, was working part-time at a furniture store, stripping the paint. It wasn't so much the thinner, or paint fumes that were beginning to burn my lungs that caused me to quit, it was more of the fact the store owner, and his brother were religious fanatics and were trying to recruit me to their congregation! I was feeling quite uncomfortable getting into a religious debate back then!
Supposedly, my mom had found the job for me, but didn't realize the fumes should have been taken into consideration.
My second job, during my junior year in high school was working at a Showbiz Pizza Place, in which I was a popular person when I was able to give out free tokens!!! (but the popularity ran out as fast as the tokens!) It was winter time, so I had plenty of contact with germs, but never really got hit by anything. I had it worse when I was working as a field tech for copy repair. I guess going in-and-out of (overly) heated buildings in the winter was rough.
I occasionally helped my little brother with his paper route, but it was rough getting up early Saturday mornings to deliver.
Whatever he finds for a job, the most important is that he enjoys it!!!
