In the book Cosmic by Frank Cottrell Boyce, Liam, the main character, is very tall so he is pretending to be a dad. Since he is still a kid, he secretly puts a Talk To Your Teen magazine in his backpack. He learns many important things from the magazine.
If I could add some suggestions to the magazine, one of them would be that all kids should eat a balanced diet without many sweets. Also, even though as a kid, you probably “strongly dislike” having chores, you should have them. Right now, we don’t use the dishwasher so I have to do the dishes and wash and fold the laundry. For allowance, I get a dollar a day if I do all my chores and I am asleep by 9:30pm. I think that all these things will be important for success later on in life. Allowance is very hard to earn because it is basically earning free money.
