My wife's sister has a son, Yuto. He has had two fathers. One promised to come back for his birthday. That was when Yuto was four. The other is Mitch. From Pennsylvania. When Mitch married my sister-in-law, Yuto was seven. For the first year, he didn't call Mitch anything. When he had to, he said "the American." "Pass the soy sauce, American." Mitch didn't mind. He was busy. He learned Japanese from Yuto's picture books. Every night he read "Momotaro" out loud, in a Pennsylvania accent so bad that one night a small voice from under the blanket said, "No. Mo-mo-TA-ro." It was the first thing Yuto ever said to him on purpose. Mitch read it wrong for the next 300 nights. Yuto corrected him every time. Neither of them ever admitted it was on purpose. The first school lunch Mitch packed had octopus-shaped sausages. They came out looking like a crime scene. The teacher called home to make sure everything was okay. Everything was okay. Except one night a year. Every birthday, after the cake, Yuto went to sit by the front window. Facing the street. Waiting. Mitch never said a word about it. He just brought two chairs. He sat there until Yuto fell asleep against his shoulder. Then he carried him to bed. Every year. Eight years. In Japan, at fifteen, a child signs his own adoption papers. Mitch kept the form in a drawer for years. He never brought it out. He told my sister-in-law, "That's his to give. Not mine to ask for." This September, Yuto turned fifteen. After the cake, Mitch went to get the two chairs. Yuto didn't go to the window. He put an envelope on the table. The adoption form. Every line he could fill, filled. His name. His signature. One empty space left. Mitch's. On top, in English, a note: "I'm done waiting at the window. He was never coming. You were already here." Mitch still can't read kanji. He didn't need to. He knew which empty line was his. He signed it. Then he went out on the balcony and called Pennsylvania. His stepfather, Earl, is 81. Later that night, Mitch told me something I never knew. When he was six, his own father promised to come for his birthday, too. He didn't come. Earl brought two chairs. On the phone, Earl was quiet for a long time. Then he said: "Told you the chairs work." In Japanese, a stepfather is "giri no chichi." A father by obligation. Mitch says half the men he grew up with were raised by a man who didn't have to. Nobody obligated Earl. Nobody obligated Mitch. Yuto calls him Dad now. The paper just caught up.
