Something about the 'ballet not turning boys gay' references in this tale of South African children learning ballet from a Russian master make me uncomfortable. Of course I understand that people say such things and have such fears but the writer could have been a little more sensitive with the framing.
Apart from that, I also have qualms about the tears and pain these children undergo. I didn't do ballet as a child but my son does. For him there are no tears, no pain. I don't think tears and pain are a good sign, even if in a good cause.
