El método Arrieta

Lourdes and Mentxu Arrieta were born with a serious problem: although they were sisters and used to spend all their time together, an illness concerning their bodies prevent them for communicating among them. They couldn't use neither voice or their hands. Till the day they found their own and original way to do it. A communacting system that was completely original and everyone around them thought it was crazy. A language that that has been totally secret for the last 30 years... till now.
