When traveling abroad or in many small towns in the states, I see what I call, 'Eking out a living'. They often do this with minimal education, since there is no large employer in town. Some fix lawn mowers, some fix radiators. This man in Barcelona only needs a bucket, soap, two sticks and some string to make some beautiful bubbles kids can play in, photographers can try to capture and all can enjoy. He got a Euro from me for me to take photos for a few minutes. I respect them trying to do what they can to eke out a living....
