It would be interesting to know more about the madness that eventually led to her suicide and what triggered it. At the moment we can only infer conclusions based on the information we have provided, but to be able to explore why such a talented and intelligent woman was struck with these issues would be fascinating.
Given the passion and intensity that comes out of Woolf's A Room of One's Own, I would ask why she did not pursue a more politically or social active stance that arises from the work. Woolf speaks with so much intensity on the issue of equality from a historical and literary point of view that seeking social or political solidarity from it would have been a natural extension. I think that I would have asked Woolf why this stance was not struck with more force. Given the Modernist movement of which she was a part, it would have made sense to articulate a form of being in the world that was not socially accepted. In seeking to bring this into reality when so much of the world was undergoing a "shift in relations," Woolf would have been able to articulate a social or political dimension to her work about what it means to be a woman and what it can mean to be one.
