Good. We’re both introverts and don’t really need to talk to each other all the time. He’s an engineer, and I’m a scientist. We both enjoy programming and solving problems (like car issues).
When I was a kid, any time I had a question or wanted to learn something, he would find a book of his to lend me or buy me my own. I used his C++, Java, and other textbooks to teach myself. He bought me drawing books and Photoshop tutorial books. I think he understood that I loved learning from an early age and didn’t really need people/human interaction to be happy.
I’m glad I impressed him for a little while when I got a few options for a free ride through college (two running offers and two service academy offers).
