She now had her own opinions, and at supper discussed with sasha's parents, saying how difficult the studies had become for the children at the school. but after all, she felt a classical education was better than a commercial course, because when you graduated from school then the road was open to you for any career at all. if you chose to, you could become a doctor, or, if you wanted to, you could become an engineer.
sasha started at the school. as his father was away every day inspecting cattle and was sometimes gone for up to three whole days at a time, it seemed to olenka that sasha was completely abandoned, was treated as if he were quite superfluous, and must be dying of hunger. so she transferred him into her part of the house and fixed up a little room for him there.
every morning olenka would come into his room and find him sound asleep with his hand tucked under his cheek, so quiet that he seemed not to be breathing.
sashenka, she said sorrowfully, get up, darling. it's time to go to school.
he got up, dressed, said his prayers, then sat down to breakfast. the sleep was not yet out of him, so he was a little cross.
you don't know your fables as you should,sashenka, said olenca, looking at him as though he were departing on a long journey. помогите перевести только не с переводчика!!!
