The little kid on the bus was sitting on his mother's lap so that his face was right under hers. They looked exactly alike, except she looked worried and he looked happy.

His big sister, maybe eight years old, sitting next to them, also looked happy. So the mother is able to use her worry to make a shelter where they can find happiness.

One reason the little kid was happy was he was learning to talk, a skill of destiny for him

He generated syllables endlessly and joyfully. I didn't understand a word, except that I did. "The bus! The people! The clothes! The colors! The sun! We're moving! We're stopping! Wow!" The hymn of now.
