Nora and Martin are two friends with a problem in common: they don t like greeting or communicating with others. They are set in their ways until they realize one day that their lack of etiquette is rendering them invisible. Will they learn the power of communication before it s too late?
Nora y Martin son dos amigos que tienen un problema comun: les cuesta saludar y comunicarse con los demas. No parecen muy dispuestos a cambiar, hasta que un dia se dan cuenta de que, a fuerza de no saludar, se estan volviendo invisibles!"
