Not only as a photographer the idea of not being able to see is unbearable. I wouldn't know what to do without my two working eyes.
Yesterday morning I saw a tube worker helping a blind man down the stairs. I thought "How nice of him!"
A few hundred metres down the road at my bus stop I saw the two again. The tube worker made that extra effort to bring the blind man to his next travel point. It really touched my heart. And re-freshed my hope in mankind a little.
Thank you tube worker! :)
