I was once ambitious and started my own insurance agency. It was a lot of work and I couldn’t yet afford to hire staff. So from time to time my oldest child, who was six at the time, would come “assist” me with simple tasks and give my spouse a rest. One time I had a pile of paperwork in the shredding bin that I hadn’t got around to yet. So I had them feeding the shredder to keep them occupied. So they were busy at work when they said, “Dad should the machine be smoking?” That’s when I realized that cheap shredders aren’t made for volume work. They also loved to run the mail through the postal meter and then run down the hall and put the mail in the slot, mostly so they could visit the gold fish pond on their way back.
