There are only two people who can speak the native Mexican language Ayapaneco. However, they are not speaking to each other.
Though it is not clear what lies behind their mutual avoidance, Manuel
Segovia (in picture below), 75, and Isidro Velazquez, 69, live 500 metres apart in the
village of Ayapa in the the southern state of Tabasco. The two have
reportedly never enjoyed each other's company.
