Answer:
"He was before my time — I never saw him;
But the pen stayed exactly as it was
There in the upper chamber of the ell,"
Step-by-step explanation:
This is the part when the parents decide to send the boy to a place where they wouldn't be bothered anymore. They were tired of the whole situation. Maybe they tried their best, but they couldn't take it. This part is haunting because her sister is the one talking to the stranger and her family has a history of mental illness. Also, her parents seem to not ever want to talk about her brother, since they never touched the pen that most likely was used to sign what sent him away.
