As I hammer away at a keyboard, my youngest brother hammers away at other things. (He’s the one in the middle. Also, his sweatshirt is not on fire, though he said it might as well have been.) I’d be proud to know, and I’d want to know, all my siblings, even if I wasn’t related to them. They’ve made families, careers, and have made my life — and the lives of many others as well — better in too many ways to count.
