Yup. I inherited my love of all things mechanical and fiddly from him-he was a machinist and had his own shop. I started sweeping the floor for ice cream when I was six or so; by the time I was in my mid-teens, I was running the machinery. That's been a while ago, but I still have grease under my nails, and my own toolbox.
He's mostly retired now, so he kinda enjoys my hobby vicariously. He's happy, I'm happy. It's all good!
