I have a brother who became a physics teacher. He reads scientific magazines. He browses the non-fiction section of book stores. He designs science experiments that involve sending a current through a pickle. (No. I'm not joking. Why do you ask?)
He often makes fun of me. That's what big brothers do. But for all that, he is supportive when I need and he loves when I knit him socks.
So I did. He has a birthday coming up. I'm pretty sure he'll be showing these off to all of his science buddies.
