When I was eight, my father did two things. He went down on his knees and begged me never to smoke. He really did. He made me promise as he knelt in front of me. It had the required impact. I was amazed at my father's zeal, and I made that promise, and I never smoked even when tempted. I just remembered. It was a clever parental move. He never smoked much and then it was a pipe, and he quit decades ago.
That same year he also taught me how to tie a tie, in case I ever had to for my husband when I grew up and got married. Pfff.
