There are so many reasons, but most of them are so simple, so embodied, that they feel inadequate to the question: She likes to hold children. To smell a baby’s hair. To soothe a crying infant and feel his little frame let go of rigid fear to settle in her arms, the weight go slack and calm so that for a moment she both gives and receives a rare peace. To rock a baby and communicate with your body: You’re safe. When she worked at the daycare she liked the thoughtless way a child would reach to take her hand. She liked watching kids puzzle out something new, their wonder, their awe and excitement, which was, when she let it be, contagious. She liked their sudden acts of altruism. She recalled this one kid at the daycare, maybe four years old, who built a tower out of blocks then tugged on her sleeve with the offer, “Do you want to kick it down?” He understood that the knockdown was the best part of building and he wanted to give it to her. Who else could give you something so pure but a child?
