When I was 5 years old my dad taught me how to carefully light a charcoal fire, way back in the days of lighter fluid. He also gave me basic tips on how to grill a steak well-done, which is the only way he'll eat meat. I learned how to cook it rare and medium-rare from a neighbor.
My dad also taught me how to assemble a gas grill and test the gas lines, but he never taught me how to do it without making a mistake and swearing up a storm. I learned the proper (non-cussing) way to assemble a grill later on my own too - it's called "reading the instructions".
