The story behind my topic choice?

I've always been interested in learning about cars every since I was a little boy. I remember always asking my dad questions when ever I seen him outside working on the cars. The reason why I chose the topic of cars cause I have always wanted to know how they were made and what material their made from. I remember one day my dad was working on the car and I asked him what he was doing and he told me he was changing the brakes on the car and I asked if I could help. My father was a mechanic and was constantly working on cars and that's all I've seen and been around in my childhood and that's why I have been interested in cars every since. I use to always ask my dad questions when I seem him working on cars and I guess one day I caught him at a bad moment and asked him a question and he asked me why was I always asking questions. I told him cause i was interested in cars and just in case one day if I had to do it to my car in the future. I would know how to do it. Like many other kids spend their spare time playing video games I was always outside with my dad asking questions about cars whenever I got the chance and was learning more more about cars every day.
