My mom worked a split-shift (3 hours in the morning, and 5 hours in evening Wed-Sun). My dad was in the army and was deployed to far-away lands for a significant portion of my life between 8-16 years old. My mom hired a couple of "minders" - but the first one made a baby in our bathroom with her boyfriend, and the second one did nothing but watch TV and sneak some shots of whiskey between TV shows (on the three networks then available).
Long story short, I was left to my own devices a lot. My mom tried to make dinner for me - but sometimes (being a growing boy) I was just really hungry - so chef-boy-r-dee pizza was a staple - at least until I learned that one could phone in an order for pizza and have it delivered! Now we were cash-poor, so when wanted spending money, I'd have to go house-to-house to ask if they needed their lawns mowed. I'd get somewhere between $5 or $10 depending on the lawn size and would use the money for pizza delivery once or twice a week.
Pretty amazing to think about it - a kid between 10-15 years old being left alone for hours a day and having to go house-to-house to mow lawns for extra money! (let's not forget it was the 70s so things like bike helmets, seat belts and non-smoking areas didn't exist either).
