When I was a child. (or you can say when we were children)

When I was eight years old and I stayed for a week at my aunt's house Anna, in Stratford Housatonic. At night, one old man came to talk with my aunt, but he was looking at my sister who is ten years old. She was sitting on a sofa with me. After he left, I sky (asked?) to my aunt: "who is he?". She said that he is a lawyer in her city, I didn't understand but my sister did. Our parents were separated. Unfortunately!!

If I wrote correct, enjoys there.

Hugs.
