I watch the beautiful performance with an ache in my chest.Then, just when I can’t stand the sadness anymore, a dancer floats out from the side of the stage. A dancer in ragged clothes, filthy and half starved. He’s not even in ballet shoes. He’s just barefoot as he glides out to take his place in the dance.The other dancers turn to him, and it’s clear that he is one of them. One of the lost ones. By the look on their faces, they weren’t expecting him. This is not part of the practiced show. He must have seen them onstage and joined in.Amazingly, the dance continues without a missed beat. The newcomer simply glides into place, and the final dancer who should have danced solo with her missing partner dances with the newcomer.It is full of joy, and the ballerina actually laughs. Her voice is clear and high, and it lifts us all.
