Freedom, please teach your son now. “Then” will be too late, esp if something should happen to you (God forbid.) My Dad began teaching me carpentry when I was 8 and even though I’m a woman, I know how to build a complete house. Even though at my age I need muscle-help, I know what to do. Building sheds and other structures…even when we bought a house, I could tell if it were well built or not. Other skills may mean the difference between life and death…again, please teach your son now.
