On a daily basis, for the parent, the eye never rests. The eye is always on two stories, unfolding at once. Two protagonists. One child climbs a chair; one reaches for an electrical outlet. One invents a new word while the other is inventing a new gesture. You cannot watch one story unfolding, then another. You cannot fall in love with one protagonist, and then another. You must fall in love with two protagonists at once. The eye looks everywhere at once, the stories unfold at once, and the heart must expand doubly.
