When you travel you experience, in a very practical way, the act of rebirth. You confront completely new situations, the day passes more slowly, and on most journeys you don't even understand the language the people speak. . . . You begin to be more accessible to others, because they may be able to help you in difficult situations.
For someone like you who's a British citizen this might seem strange. How can you ban a language? It turns out that you can. During the dictatorship it was illegal to speak Catalan. This is an experience that we Catalans have all had to varying extents. Some more tense than others, but it's something we all share.
