Thirty-five years ago today, my mother employed her primary Superpower and made a person. A day or two later I was introduced to a lifetime companion and playmate and co-conspirator and friend: my sister Karin. (She guides people’s pronunciation with this clue: “You park a KAR-in the garage.”) I turned three just a few weeks before her arrival, and my game du jour was tagging people with their initials. My new sister’s “KD” became Kadi to the family—a name that stuck permanently.  (With the occasional variation, such as “Aunt Tadi” when my son Christian was little and couldn’t pronounce K.)

Kadi and her husband Scott visited from Seattle last weekend, and Keoni told me he was getting a kick out of watching the two of us, noting the facial expressions and mannerisms we have in common. It’s a funny thing, how amazingly alike we are, despite our very different lives. Even some of our random OCD eccentricities are a match, like our refusal to eat the last bite of a sandwich—the piece we’ve been holding while we ate the rest. Can that possibly be genetic? It certainly wasn’t something we learned together—we discovered the quirk-in-common as adults, when we met each other for lunch one day.

I don’t see my sister in my mirror, but I see her all the time in my photos. We insisted for years that we didn’t look anything alike (despite being taken for twins with some regularity), but then I began to mistake pictures of her for pictures of myself… When she first moved to Boise after graduating from Law School, she reported getting hug-attacked in REI by a perfect stranger—someone who obviously knew me well enough to hug me, but still couldn’t tell that she wasn’t me. I have occasionally gotten responses like “Duh” and “No shit” when I point her out or introduce her as my sister. Apparently it’s obvious.

Our family traveled a lot when we were growing up, so we were often the only available playmates for each other. Happily, we got along pretty well together—barring the occasional scuffle or argument, we enjoyed like minds and tastes and imaginations most of the time. Our mother has said of our six-month trip through Europe that we fought the first day, and then it seemed to dawn on us both that we would only have each other for the next half-year… So we made up—and stayed made-up for the rest of the tour.

Our friendliness is, in itself, a testament to my sister’s amiable nature. It’s not easy being anyone’s younger sister. She has gone on, though, to distinguish herself in arenas of her own—clerking for a judge on the Ninth Circuit Court of Appeals, working as a Deputy Attorney General for the state of Idaho, and now with a prominent law firm in Seattle. We’re pleased with the idea that we both make our livings at writing—legal briefs in her case, and random oddities in mine…

We used to write plays together, and perform them for the captive audience of our parents and grandparents. We had to make creative allowances for the small size of our cast, which led to some memorable adaptations like “Snow White and the One Dwarf,” in which she played the princess and I played everyone else.

Keoni introduced me to the idea of the ‘aumakua—the totem or guardian in Hawai’ian culture—and last summer it became clear to me that the Owl is mine. Owls were crossing my path, night and day, every time I was on the road with a writing assignment… When I wrote about the topic here, Kadi emailed me, expressing astonishment because she had developed a particular affinity for owls in the last year as well. I wasn’t expecting that, of course, but at the same time it didn’t surprise me. (I figure it’s our “Irish” coming out… Owls are totems in Celtic culture too.) Besides, we’ve always seemed to be on the same wavelength, even though our lives are outwardly so different.

Speaking of Hawai’ian culture, Keoni has asked me to tell her “Hau’oli la hanau.” When we say it aloud (how OH-lee lah huh-NOW), people often respond by telling us their age, thinking we’ve asked them, “How old are you now?” But it actually means—from both of us—Happy Birthday!
