Hello goncin!
I've rejected the translation of this text here and I've translated it again according to Kafetzou's brdige there. But I'm not sure about if "detention" means something like "detention centre"? Could you explain please?
I've already read it more than three times but it seems I was not being careful so I read very carefully your explanation and I understand what it means now ("building" :yes
thank you very much goncin!!
