At Baby Gap, a mother buys her twin daughters matching pink mary janes with floral embroidered trim. They are sitting barefoot, side by side, in a double stroller.

The girl on the right cries when her mom hands the shoes to the cashier. "Mommy, my shoes! I want my shoooeess!" she hollers.

The girl on the left notices me looking at them and smiles. She has a front tooth missing, or maybe it's a gap between teeth. Still, she smiles a big, beaming, toothless grin. Then she plays hide and seek with me through the mesh back of the stroller, giggling up a storm.
