I press my forehead into Hazel’s—a gesture made marginally awkward since she just recently surpassed me in height. “I love you too.” I hold the sign against her collarbone. When she pulls away, she replies, “Want to practice your vows one more time?” “My vows to you or to him?” I reply with a laugh and she rolls her eyes in teenage perfection. “I didn’t demand vows. I politely requested a sibling as soon as possible. I’ve waited long enough.”
