Was Sasha kind when he was a child?

Sasha was very kind when she was a child. When I was a child, there were two Sasha, Sasha of Heller's family: gentle, quiet, never conspicuous, always sitting alone in a dark corner. Sasha of Yakov family: He is a good boy. He always revolves around adults and is good with everyone. He will obey anyone who asks him to do anything. He always looks around, as if waiting for an opportunity.
