The dialogue addresses the issue of closeness, proximity and the ways in which human societies interact with each other through commercial exchange, migratory dynamics, and culture. The discussion focuses on the Northeastern border of Mexico and Texas as a space of union and not just a space of division. Whereas borders are generally thought of as spaces in dispute and conflicts that encapsulate and separate countries, borders also mean contiguity, and contiguity very often produces interaction. This is especially the case of the border along the Mexican states of Tamaulipas, Coahuila and Nuevo León, and the state of Texas.
