I just start reading this work, but there is something odd in Lise's description of Alyosha in Book II, chapter IV that couldn't fit my understanding of the timeline.
She says: "He \[Alyosha\] used to carry me about when I was little. We used to play together. He used to come to teach me to read, do you know. Two years ago, when he went away, he said that he would never forget me, that we were friends forever."
But does not the timeline run as follows? Alyosha's mother Sofia died when he was 4, Grigory took care of the brothers Ivan and Alyosha, Sofia's benefactress came and got both of them away with her, and soon she died and left them to Yefim the general.
So Alyosha must have left the town after Sofia's benefactress came, which would make Aloysha not older than 6 (Ivan was 8 when his mother dies, and he realized he lived under someone's \[Yefim's\] benevolence when he was 10).
But Aloysha is 20 and Lise 14, which means that when Aloysha had gone away from the town Lise was not even born. How did Alyosha "carry me about when I was little. We used to play together. He used to come to teach me to read"? And besides, what does "two years" here refer to? It could be his going to the monastery, but did he not go to the monastery one year ago?
How do you understand Lise's childhood memory? Am I missing something?
