We ate as a family, whomever was cooking that night cooked for everybody. I cooked my first meal for our family when I was 10 years old. I started regularly cooking for the family when I was about 13. I would say at that point I was cooking four nights a week and my mom or dad the other three.
I'm 17 and currently just started cooking most of the meals, but I do it because I adore cooking and my dad has been teaching me. Besides, I'd rather learn before I move out than be forced to learn when I'm on my own.
