Duras Day I

The dynamic between Anne and her son is odd because it seems to change drastically from the first chapter at the piano lesson to the second chapter at the bar.
During the piano lesson, the boy is treated more like an object that needs to be molded into the form his mother wants him to be. She wants him to learn piano because she thinks the music is beautiful, not because he enjoys it. And instead of defending him when the piano teacher is cruel to him, she agrees and says how difficult he is, when really he isn't being difficult so much as unresponsive. He doesn't throw fits or argue, he just refrains from giving the adults what they want, which is ultimately to treat him like something other than a child.
Later the next day at the bar, Anne suddenly seems like a loving, protective mother. She talks about how she always brings her son for a walk. However her real motivation for coming is her curiosity about the murder and she lets him wander away from her.
Her fascination with the murder is somewhat strange to me and it seems that there is something more to the story that we as readers don't know yet. When she is talking to the man it says that she "lies" about knowing about the murder. This may be a further attempt to conceal her curiosity which she may think is indecent, or there may be something more to it.
