Most of us old farts have stories about how hard we worked as kids.
Back in the day, my best pal's dad was a general contractor. He'd employ us on Saturdays and over vacation days. Paid us $10-a-day for framing, nailing down sub flooring, pushing loads of cement, stacking lumber, or just about anything else nasty, dusty, hot, or hard that came up.
Those times he didn't have any work were filled with us straightening up his shop, cleaning up the yard, changing oil in the gas-powered equipment, or just messin' about with some of his power tools--and that was all for free.
As a reward for some of the "free" labor, the old man gave us an old Briggs and Stratton engine and access to his welding equipment. We built us a go-kart. And the results nearly killed off his work force.
I hadn't thought about this stuff for ages until I started reading this thread.
Man, I miss those days... (sigh)
