Amid all the stress leading up to Younger Brother’s surgery—it went well and I am so grateful for everyone who sent supportive words—we had a good family event. My wife changed her name and legal gender: she is now she and her and wife. (She has been going by Mom with the kids for some time.)
I’ve added a note on my About page to help any future readers who might stumble upon my archives. I’m still married to—and very much in love with—the same wonderful person.
