Where was Mary when she was sexually assaulted, and what was her reaction to the event?

When Mary was seven years old, she was sexually assaulted by a neighborhood boy while playing a game called "torture." At the time of the attack, Mary knew, somehow instinctively, that her mother would not be able to cope with the news of the abuse, so she decided to keep quiet. Now, as an adult writer, Mary addresses her attacker personally and asks him questions about his motivations.
