You don’t see the head of bouncing dark hair, barreling toward you. You don’t notice anything until a tiny body slams right into your leg, and little arms wrap around your knees. You look down in shock, rocking back to steady yourself so that you don’t topple right over. Your phone nearly slips out of your hand, right onto the head of the very small human peering up at you with big round eyes. It’s a little girl.
