求翻译：The woman began to thank us and bless us, and could not make enough of it. Just then I noticed, in one corner of the bare, dark room, a boy kneeling in front of a chair, with his back turned towards us, who appeared to be writing; and he really was writing, with his paper on the chair and his inkstand on the floor. How did he manage to write in the dark? While I was saying this to myself, I suddenly recognized the red hair and the coarse jacket of Crossi, the son of the vegetable peddler, the boy with the useless arm. I told this to my mother softly, while the woman was putting away the things.是什么意思？
