What are some good parenting hacks?

I was recently on vacation with my family and my housekeeper accidentally ruined my clothes dryer. It was actually my fault, as I didn't have time to warn her not to leave it on after she finished drying, because then it would short out and could burn. Well, it did, however, the end of the story is pretty good, as the guys from https://serviceservotech.com/2022/08/%d1%81lothes-dryer-repair-service/ quickly fixed the problem and now it works again.
