Dear Primo: a letter to my cousin

Here comes the story of two cousins, one in America and one in Mexico, and how their daily lives are different yet similar. Charlie takes the subway to school; Carlitos rides his bike. Charlie plays in fallen leaves; Carlitos plays among the local cacti. This story covers the sights, sounds, smells, and tastes of two very different childhoods, while also emphasizing how alike Charlie and Carlitos are at heart.
