Her son is mentioned on the first page as the result of a brief affair whrn she was in Italy.

Thanks for that. I got to the final page and wondered where the hell the son appeared from!

I think her words that if she could tell her son something more, it would be that in the end, none of it matters speaks volumes for her lot in life.
