My mom had two.
Sister and I cleaned our rooms, each took a bathroom, dusted the living room furniture and alternated nights washing dishes. At 16 we did our own laundry. Mom was no dumbass, and certainly had never heard of child labor laws. I bussed tables at a family friends restaurant every Friday and Saturday night starting at 14. Started me down a bad path.... Waitresses taught me how to drink, smoke, Gamble and a few other things I shouldn't have known at that age!
